Crystal structure and spectroscopic properties of a one-dimensional copper(I) coordination polymer: mu-ethylene bis(diethyldithiocarbamate) copper(I)perchlorate. [Cu(EDTC)(2)]ClO4[EDTC =ethylene bis(diethyldithiocarbamate)]

The synthesis and X-ray structure of the one-dimensional polymeric ethylene bis(diethyldithiocarbamate) copper(I) perchlorate complex formulated as [C u(EDTC)(2)](n) .(ClO4)(n) were reported. The copper ion is tetrahedrally co ordinated by four sulfur atoms from four different ligand molecules. Each o f the ethylene bis(diethyldithiocarbamate) ligands bridges two copper(I) io ns. The shortest Cu-Cu distance is 8.361(3) Angstrom. This bidentate, non-c helating coordination leads to a one-dimensional chain. The structure of th e title compound in solution was also studied by electrospray mass spectrom etry (ESMS). This study demonstrates that a one-dimensional chain polymer c ould be retained in solution as the same structure as in solid. (C) 1999 El sevier Science Ltd. All rights reserved.
