The reactions of the phosphinoborane Ph 2 PBH 2 · NMe 3 with Cu (I) halides [CuCl, CuBr, CuI] and [Cu(CH 3 CN) 4 BF 4 ], respectively, were studied. Depending on the ratio of the reactants used, the former reaction allowed for the synthesis of eight neutral coordination compounds with the general formula [Cu n X n (Ph 2 PBH 2 · NMe 3 ) m ] (X = Cl, Br, I; n = 1, 2, 4, 5; m = 2, 4) ( 4–11 ). The latter reaction, however, led to the formation of the homoleptic complex [Cu(Ph 2 PBH 2 · NMe 3 ) 3 ][BF 4 ] ( 13 ). The structures of the products 4 – 11 and 13 were compared to related complexes possessing the well‐known Ph 3 P ligand. All compounds were characterized by single crystal X‐ray structure analysis, multinuclear NMR spectroscopy, IR spectroscopy and mass spectrometry.
