SYNTHESIS AND X-RAY CRYSTAL STRUCTURE OF A COPPER(II) COMPLEX WITH PYRIDOXAL-AMINOGUANIDINE (PLAG) LIGAND

With the re-ac-tion of warm wa-ter mix-tu-re of pyri-do-xal hydroc-hlo-ri-de (PL.HCl), and Ami-no-gu-a-ni-di-ne-hydro-gen-car-bo-na-te (AG.H2CO3) in pre-sen-ce of Na2CO3·10H2O, pyri-do-xal-ami-no-gu-a-ni-di-ne (PLAG; H2L) was ob-ta-i-ned. Li-gand and ap-pro-pri-a-te salt CuCl2 are co-or-di-na-te, and form the fol-lo-wing com-plex: green-brown, he-xa-co-or-di-na-ted, oc-ta-he-dral struc-tu-re, dim-mer-com-plex Cu(II) for-mu-la [Cu(PLAG)(NCS)2]2. This pa-per pre-sents a synthe-sis and crystal struc-tu-re of com-plex with Schiff-ba-sed li-gand.
