After reaction of benzene-1,2-dithiol (bdtH2) with ammonium [99Tc] pertechnetate in aqueous alcohol, extraction of the reaction mixture with chloroform yielded wine-red crystals of the title compound, C24H16S8Tc2.CHCl3. The crystal structure of the binuclear complex has been determined by X-ray diffraction. Crystals are triclinic and belong to the space group Pī with a 8.534(1), b 8.842(2), c 11.192(3)Ǻ, α 107.02(2), β 98.13(1), γ 100.60(2)° with Z 1. Refinement on 1524 data measured with Cu Kα radiation converged at R 0.082. The complex has exact Ci point symmetry and pseudo-C2 symmetry. Each technetium atom is coordinated to a trigonal -prismatic array of six sulfur ligand atoms. These arrays are fused through a quadrilateral face defined by the four bridging sulfur atoms of two benzene-1,2- dithiolato ligands to give a Tc2S8 core of D2h pseudo-symmetry. As a Tc - Tc bond [bond length 2.591(3)Ǻ] passes through the mid point of the quadrilateral face, this novel geometry can be described in terms of capped trigonal prisms. The chloroform is disordered.

A new Cu(II) complex with bi-[N-(propionic acid)] terephthalal diacythydrazon (H4L) was obtained by the reaction of CuCl2•2H2O and H4L in 1:1 pyridine and methanol. According to X-ray diffraction, the product was a binuclear complex, [Cu2L(pyridine)6]•2H2O. Each Cu(II) in the complex is six-coordinated by one N and two O atoms of H4L and three N atoms from pyridine. The coordination polyhedron around Cu(II) can be described as an octahedron with slightly distorted. Inaddition, antibacterial activities of the complex against coliform were investigated. The results showed that the inhibit rates of binuclear complex were 83% against coliform.
