Abstract
The new title two- dimensional coordination polymer [Cu2C(C6H4NO2)3(H20)2]n. (1), consists of an asymmetric unit which contains two crystallographically independent copper (I) centers { [bis(w-CI)(M-C6H5NO2-K4N:N:0,013Cu(Il)] and I(H-C6H5N02-k30:N:O)3(H20)2Cu(Il)] for Cu2 and Cu1 respectively} bridged by iso-nicotinate ( L) anion." The bridged L coordinated as a monodentate through O-atom of the carboxylate group to Cul, while the N-atom coordinated to Cuz. The Cu adopts a distorted octahedral geometry formed by two -atoms from two different L anions, carboxylate oxygen atoms as a chelate from another Lanion, and two chloride atoms. Cu1 adopts a highly distorted square pyramidal by two monodentate carboxylate oxygen atoms from two different L ligands, N-atom from another ligand L and two oxygen atoms from two coordinated water molecules. There is a - interactions between neighboring pyridine rings within the same 2D framework. Hydrogen bonds are present in the crystal structure.
