Synthesis and crystal structure of Zinc (II) Complex [Zn(25-MBTSC)2I2]

Zinc (ii) complex, [zn(25-mbtsc)2i2] (1), where (25-mbtsc = (e)-2-(2,5-dimethoxybenzaldehyde) thiosemicarbazone, has been synthesized from the reaction of zni2 with 25-mbtsc in methanol as solvent at 25 ?c. it was characterized by elemental analysis (chn) and is confirmed by single-crystal x-ray diffraction analysis. the complex 1 crystallizes in a triclinic system, with space group p-?, having one symmetry-independent zn2+ ion coordinated in a distorted tetrahedral geometry by two s atoms of the 25-mbtsc ligand and by two i atoms. the thiosemicarbazone ligand 25-mbtsc acts as a monodentate ligand and coordinates via one s atom in ?1-s bonding mode to the zinc center.
