A MIXED (ARENETHIOLATO)COPPER(I) COPPER BROMIDE AGGREGATE - X-RAY STRUCTURE OF OCTANUCLEAR [CU-8(SC6H3(CH(2)NME(2))(2)-2,6)(3)BR-5]/

The complex [Cu-8{SC6H3(CH(2)NMe(2))(2-)2,6}Br-3(5)] (4) is the first reported example of a mixed (thiolato)copper/copper halide aggregate. Its X-ray structure shows it to be a fully asymmetric molecule compris ing three copper arenethiolate and five copper bromide entities and ha ving a distorted square-antiprismatic arrange ment of the octanuclear copper core. Some structural features of the bonding of the bromine an d the sulfur atoms are common to known aggregate structures, but the s tructure does show an unprecedented mu(4)-S-bonding of one arenethiola te ligand.
