A novel methylene dithioether as a ligand: Synthesis and molecular structure of a zinc(II) complex with N4S2 coordination environment

摘要

The octadentate ligand [N(CH2CH2NH2)(CH2CH2CH2 OH)(CH2)CH2S)](2)CH2, (NNOS-232)(2)CH2, was synthesized accidentally by the reaction of the unsymmetrically substituted tripod [N(CH)CH2)NH2)(CH2CH2CH2OH)(CH2CH2)SH)], NNOS-232, with dichloromethane in the presence of aluminum hydroxide. Ligand (NNOS-232)(2)CH2 was reacted with zinc bis(perchlorate) hexahydrate to yield the complex [Zn((NNOS-232)(2)CH2)](ClO4)(2) exhibiting a distorted octahedrally coordinated zinc atom in an N4S2 coordination environment, as shown by an X-ray diffraction study.
