| Abstract: | Abstract The reactions of a new compound of N-Carboxyphenylenesulfonyl-S-Carboxymethyl-l-Cysteine (Cs-cmc) with Zn(II) or Co(II) salts in the presence of 4,4′-bipyridine (4,4′-bipy) led to the decomposition of
Cs-cmc and produced Zn(4,4′-bipy)(H2O)4]X2 (X = p-sulfamoylbenzoate) 1 and Co(4,4′-bipy)(H2O)4]Y·H2O (Y = p-sulfonatobenzoate) 2, in which the decomposition products of Cs-cmc exist as free counter-anions. The single crystal X-ray diffraction analyses
revealed that compound 1 crystallizes in monoclinic C2/c space group with a = 18.748(4) ?, b = 11.520(2) ?, c = 12.751(3) ?, β = 90.290(4)°, V = 2753.9(10) ?, Z = 4 and compound 2 crystallizes in orthorhombic Pca21 space group with a = 12.114(3) ?, b = 11.369(2) ?, c = 14.770(3) ?, V = 2034.1(7) ?, Z = 4. It was revealed that 1D chains were constructed from metal ions and 4,4′-bipy in both compounds. The 1D chains interact
with the counter-anions by hydrogen bonds, forming 3D supramolecular structures. |
