Synthesis, Crystal Structure and Antibacterial Activity of a Calcium(II) Complex of 2-Formyl-benzenesulfonato-hydrazine

摘要

A Schiff base complex, [Ca(L)-(H2O)4]4H2O, has been synthesized and structurally characterized by elemental analyses and X-ray diffraction. In the complex, the Ca(II) atom is six-coordinated by two O atoms from the Schiff base ligands, 2-formyl-benzenesulfonato-hydrazine and four O atoms from four coordinated water molecules, forming a slightly distorted octahedral CaO6 geometry. The complexes form one-dimensional chained structure by intermolucules and intramolecules hydrogen bonds and π-π interaction of benzene rings. The antibacterial activity of the Ca(II) complex indicates that the Ca(II) complex shows considerable antibacterial activity against Escherichia coli, Bacillus suhtilis and Staphylococcus white.
