Lewis-Base Adducts of Group 11 Metal(I) Compounds. L. Heterobimetallic Tris(dithiocarbamato)metal(III)/Copper(I) Iodide Adducts [Metal(III) = Cr, Rh]

Abstract

A variety of heterobimetallic adducts formed between tris(dithiocarbarnato)cobalt(lII) complexes and copper(1) halides have been recorded. In the present paper, reports of the synthesis and structure determinations of [Rh {S₂CN(CH₂)₄}₃]₃Cul (1), [Cr(S₂CNEt₂)₃]. [Cr(S₂CNEt₂)₃] and [Cr{S₂CN(CH₂)₄}₃].3Cul.MeCN (3), similar to cobalt(llI) counterparts, suggest that, in principle, the previously described chemistry of the cobalt(III) systems may be extended to analogous systems for dithiocarbamates of any non-labile trivalent metal. The novel Cu₃I₃ ring of (3) is disordered between possible boat forms.
