Abstract
Synthesis and Crystal Structures of the Phosphaneimine Complexes [Cu(μ-HNPEt3)]4(O3S–CF3)4 and [Pt2Me6(μ-I)2(μ-HNPMe3)] The title compounds have been prepared by the reaction of copper(I)triflate with [NiBr(NPEt3)]4 in CH2Cl2 suspension in the presence of water, and by the reaction of [PtMe3I]4 with Me3SiNPMe3 in boiling toluene in the presence of cesium fluoride, respectively. According to the crystal structure determinations the cation of the copper complex forms tetrameric units [Cu(HNPEt3)]44+ with S4 symmetry with Cu–N bond lengths of 191.6 and 192.1 pm. In the platinum complex the platinum atoms are linked by two μ-I bridging atoms as well as by the μ-N atom of the HNPMe3 ligand with Pt–N bond lengths of 228.1 and 229.5 pm.
