Biocoordination and Computational Modeling of Streptomycin with Co (ii), Ni (ii), in (ii) and Inorganic Sn (ii)

The coordination compounds of streptomycin with Co(II), Ni(II), In(III) and Sn(II) have been synthesized and characterized by elemental analysis, vibrational spectra, electronic spectra, HNMR spectra, magnetic susceptibility measurement ,thermal studies and Xray powder diffraction studies. The complexes having crystallographic datas as a=21.9909(Å), b=13.12141(Å), c=11.88511(Å), V=3429.47(A), for complex 1; a=6.904155(Å), b=12.57103(Å), c=13.77902(Å), V=1090.3(A) for complex 2; a=6.709547(Å), b=9.231634(Å), c=8.6857(Å), V=347.1999(A) for complex 3 and a=16.10349(Å), b=10.4157(Å), =9.588465(Å), V=16084.26(A) for complex 4. The results of spectral techniques kinetic parameters were computed from the thermal data using Coat and Redfern method, which confirm first order kinetics. Molecular structures of the complexes have been optimized by MM2 calculations and supported octahedral, trigonal planar /tetrahedral geometry around Metal (II) ions and In (III) ions.
