[NPrn4]2[(ReS4)Cu5I6] and [NEt4]2[(ReS4)Cu3I4]: novel low dimensional solids
Abstract
The compounds [NPrn4]2[(ReS4)Cu5I6]1 and [NEt4]2[(ReS4)Cu3I4]2, containing polymeric heterometallic chains and interesting structural features according to X-ray structure analyses, have been obtained by reaction of CuI with [NPrn4][ReS(S4)2] in dichloromethane 1 or [NEt4][ReS4]2 in acetone; complexes 1 and 2 are examples of a series of compounds which prove the possibility of a stepwise ‘capping’ of the edges of an ReS4 tetrahedron by a Cu(hal/pseudohal)x fragment (x= 1,2).
