Influence of filled dπ-manifold and L/L′ ligands on the structure, basicity, and bond rotations of the octahedral and d6 amido complexes TpRu(L)(L′)(NHPh) (Tp = hydridotris(pyrazolyl)borate;: L= L′ = PMe3 or P(OMe)3, or L = CO and L′ = PPh3):: Solid-state structures of [TpRu(PMe3)2(NH2Ph)][OTf], [TpRu{P(OMe)3}2(NH2Ph)][OTf], and TpRu{P(OMe)3}2(NHPh)
