Diastereomeric metallatetrahedron complexes of the type Re2(MPPh3)(M′PPh3)(μ-PCy2)(CO)7(−)-thiocamphanate (M = Ag, Au, M′ = Cu, Ag, Au): synthesis, structure and CD data
Abstract
Four pairs of diastereomeric metallatetrahedron complexes of the type Re2(MPPh3)(M′PPh3) (μ-PCy2)(CO)7(−)-thiocamphanate have been synthesized, with identical (M = M′
= Au (5a, 5b) and Ag (6a, 6b)) and with mixed coinage metals (M = Au, M′
= Ag (8a, 8b) and Cu (9a, 9b)). After separation, the absolute configuration was determined by
