Contributions to the chemistry of silicon-sulphur compounds—LXI. The first neutral monomeric copper(I) thiolate complex. Crystal and molecular structure of (1,10-phenanthroline)(tri- tert-butoxysilanethiolato) copper(I), [Cu{SSi(OC 4H 9-t) 3}(phen)

Abstract

The title compound [Cu{SSi(OC 4H 9- t) 3}(phen)] ( 1), the first monomeric neutral copper(I) thiolate complex was obtained by reaction of 1,10-phenanthroline with [( t-BuO) 3SiSCu] 4 in benzene and its crystal structure determined. The copper atom is threefold coordinated to one sulphur atom and two nitrogen atoms in a nearly trigonal planar arrangement. The relevant bond distances and angles are CuN 203.1(2) and 210.8(3) pm, CuS 214.0(1) pm, SSi 208.6(1) pm, NCUN 80.9(1)°, NCuS 133.5(1)° and 144.6(1)°, and CuSSi 102.1(1)°.
