A crystallographic and spectroscopic investigation of the stereochemistry of [MBr(CO)3L2] (M=Mn, Re) complexes: crystal and molecular structures of [MBr(CO)3L2] {M=Mn, L=P(C6H4Cl-4)3, 1/2dppe, 1/2dppf; M=Re, L=P(C6H4OMe-4)3, 1/2dppf}

Abstract

A series of [MBr(CO)3L2] complexes {M=Mn, L=P(C6H4Cl-4)3 (1), P(C6H4OMe-4)3 (2), P(CH2C6H4)3 (3), 1/2dppe (4), 1/2dppb (5), 1/2dppf (6); M=Re, L=P(C6H4Cl-4)3 (7), P(C6H4OMe-4)3 (8), P(CH2C6H4)3 (9), 1/2dppp (10), 1/2dppb (11), 1/2dppf (12)} were synthesised and characterised by elemental analysis, m.p., IR and 31P-NMR spectroscopy. With the exception of 4, all compounds are previously unreported. Five selected examples (1, 4, 6, 8, and 12) were characterised by single crystal X-ray diffraction studies. These studies confirmed fac,cis geometries for Re(I) derivatives and all complexes with bidentate ligands; the remaining Mn(I) derivatives had mer,trans geometries.
