B. Thimme Gowda,Sabine Foro,K. Shakuntala
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811020319
Abstract: The structure of the title salt hydrate, K+·C6H4Cl2NO2S ·H2O, shows each of the sulfonyl O and water O atoms to be bidentate bridging. The heptacoordinated K+ cation is connected to two water O atoms, four sulfonyl O atoms and one Cl atom. The crystal structure comprises sheets in the bc plane which are further stabilized by O—H...N hydrogen bonds.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811039109
Abstract: In the crystal structure of the title compound, K2[B10O14(OH)4]·H2O, the polyborate [B10O14(OH)4]2 anions are linked together through their common O atoms, forming a helical chain-like structure. Adjacent chains are further connected into a three-dimensional structure by O—H...O hydrogen bonds. The water molecules and potassium cations are located between these chains. Further O—H...O hydrogen bonds occur between the anions and the water molecules

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809005637
Abstract: The title salt, poly[aqua-μ3-oxalurato-potassium(I)], [K(C3H3N2O4)(H2O)]n, which was obtained from a water solution of oxaluric acid and KOH at room temperature, crystallizes as potassium and oxalurate ions along with a water molecule. The K+ cation lies on a crystallographic twofold rotation axis (site symmetry 2, Wyckoff position f), and the water and oxalurate molecules are located within different mirror planes (site symmetry m, Wyckoff position g). The K+ cation is eight-coordinated by six O atoms of six oxalurate ligands and two O atoms from two water molecules in a distorted square-antiprismatic geometry. All of the eight coordinated O atoms are in a monodentate bridging mode, with alternate bridged K...K distances of 3.5575 (12) and 3.3738 (12) . The oxalurate ligand shows a μ3-bridging coordination mode, which links the K+ cation into a three-dimensional network. The oxalurate ligands and the water molecules are involved in inter- and intramolecular N—H...O, and O—H...O hydrogen bonds, which stabilize the network.

Acta Crystallographica Section E , 2012, DOI: 10.1107/s160053681201094x
Abstract: In the title compound, C19H17NO3S2, the morpholine ring is in a chair conformation. In the coumarin ring system, the dihedral angle between the benzene and pyran rings is 3.9 (1)°. In the crystal, weak C—H...O interactions link the molecules into corrugated layers parallel to (102). The crystal packing also exhibits π–π interactions, with distances of 3.644 (1) and 3.677 (1) between the centroids of the benzene rings of neighbouring molecules.

Acta Crystallographica Section E , 2013, DOI: 10.1107/s1600536812051847
Abstract: In the title compound, C16H17NO4S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.070 (1) , and the morpholine ring adopts a chair conformation; the bond-angle sum for its N atom is 357.9°. The dihedral angle between the the 2H-chromene ring and the best plane through the morpholine ring is 89.09 (6)°. An intramolecular C—H...S hydrogen bond occurs. In the crystal, C—H...O hydrogen bonds generate R22(8) rings and π–π interactions occur between fused benzene rings of the chromene system [shortest centroid–centroid distance = 3.5487 (8) ].

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812047174
Abstract: In the title adduct, 2C6H5NO3·C4H9NO, the morpholine ring adopts a chair conformation. The dihedral angle between the two nitrophenol rings is 69.47 (9)°. The nitro groups attached to the benzene rings make dihedral angles of 3.37 (16) and 3.14 (13)° in the two molecules of nitrophenol. The crystal structure is stabilized by N—H...O, O—H...N and O—H...O hydrogen bonds and further consolidated by C—H...O interactions, resulting in a three-dimensional network.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808019429
Abstract: In the crystal structure of the title compound, K+·C6H4IO3S ·H2O, the potasium cation is 2.693 (3)–2.933 (3) from the sulfonate and water O atoms (including symmetry-related atoms) and forms a two-dimensional sheet-like structure in the bc plane, with the iodobenzene rings protruding above and below. The water molecule of crystallization is hydrogen-bonded to sulfonate O atoms within this two-dimensional arrangement. Symmetry-related iodobenzene rings are arranged perpendicular to one another with the I atom ca 4.1 from the centroid of the neighbouring benzene ring. In the crystal structure, these two-dimensional sheet-like supramolecular structures are arranged parallel to one another, stacked along the a-axis direction, with the benzene rings interdigitated.

Abstract: a few mixed ligand transition metal carbodithioate complexes of the general formula [m(4-mpipzcdt)x(phen)y]y (m = mn(ii), co(ii), zn(ii); 4-mpipzcdt = 4-methylpiperazine-1-carbodithioate; phen = 1,10-phenanthroline; x = 1 and y = 2 when y = cl; x = 2 and y = 1 when y = nil) were synthesized and screened for their antimicrobial activity against candida albicans, escherichia coli, pseudomonas aeruginosa,staphylococcus aureus andenterococcusfaecalis by disk diffusion method. all the complexes exhibited prominent antimicrobial activity against tested pathogenic strains with the mic values in the range <8-512 μgml-1. the complexes [mn(4-mpipzcdt)2(phen)] and [co(4-mpipzcdt)(phen)2]cl inhibited the growth of candida albicans at a concentration as low as 8 μgml-1.the complexes were also evaluated for their toxicity towards human transformed rhabdomyosarcoma cells (rd cells). moderate cell viability of the rd cells was exhibited against the metal complexes.
