Abstract: In the centrosymmetric dinuclear title complex, [Cu2(C5H6O4)2(C12H18N2)2(H2O)2], the CuII atom displays a distorted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water molecule is located at the apical position. Of the two water H atoms, one is engaged in an intramolecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an intermolecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π–π stacking interactions involving symmetry-related phenanthroline rings [centroid–centroid distance = 3.5599 (17) and 3.5617 (18) ], building a three dimensionnal network. C—H...π interactions involving the phenanthroline ring system are also observed.

Abstract: The molecule of the title compound, C9H8Br2O3, is stabilized by an intramolecular O—H...O interaction. Intermolecular C—H...O interactions connect molecules into a two-dimensional array in the bc plane; connections between these are afforded by π–π stacking interactions [centroid–centroid distance 3.596 (5) ].
Generating an entangled coherent state of two cavity modes in a three-level Λ- type atomic system
Qing-Xia Mu,Yong-Hong Ma,L. Zhou
Physics , 2007, DOI: 10.1088/0953-4075/40/16/005
Abstract: In this paper, we present a scheme to generate an entangled coherent state by considering a three-level \Lambda - type atom interacting with a two-mode cavity driven by classical fields. The two-mode entangled coherent state can be obtained under large detuning conditions. Considering the cavity decay, an analytical solution is deduced.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810039127
Abstract: In the title compound, C20H17N3O3, the dihedral angles between the central pyridine ring and the two terminal rings are 15.07 (3) and 43.24 (3)°. The dihedral angle between the two terminal rings is 37.49 (4)° In the crystal, intermolecular amine N—H...Nnitrile hydrogen-bonding interactions form inversion dimers, which are linked into chains through amine N—H...Omethoxy hydrogen bonds.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809028141
Abstract: The title compound, C26H38O6·H2O, is a mono-ester of a derivative of maleopimaric acid, an abietic-type acid. The two fused and unbridged cyclohexane rings adopt approximate chair conformations while the three other three six-membered rings have boat conformations.

Abstract: The title compound, C24H32O5·C2H4O2, is a derivative of abietic acid. The two fused and unbridged cyclohexane rings have chair conformations and the anhydride ring is planar. Of the other three six-membered rings, two have boat conformations and one has a twist-boat conformation. The crystal structure is stabilized by intermolecular O—H...O and C—H...O hydrogen bonds.

Abstract: In the title compound, C18H22N2, which possesses non-crystallographic inversion symmetry, the central piperazine ring adopts a chair conformation. The phenyl rings are not exactly parallel and make a dihedral angle of 1.3 (1)°. No significant intermolecular contacts are observed in the crystal.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811002698
Abstract: In the title compound, C25H32O7, the 3-hydroxy-5,5-dimethylcyclohex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intramolecular hydroxy–ketone O—H...O interaction between the two substituted cyclohexane rings as well as a short intramolecular phenol–methoxy O—H...O interaction.
