Abstract

The reactions of the Re(V) starting material [ReO(PPh₃)₂Cl₃] with ligands of the type XN(Y)Z [X = Y = 2-pyridylmethyl, Z = -CH₂CO₂Et (L¹Et), -CH₂CH₂CO₂Et (L²Et), -CH₂CH₂CH₂CH₂CH (NHCO₂Bu^t)CO₂H (L³H); X = 2-pyridylmethyl, Y = 2-(1-methylimidazolyl)methyl, Z = -CH₂CO₂Et (L⁴Et)] yielded the Re(III) trichloride complexes of the type [ReCl₃(LⁿR)]. The complexes are mononuclear, paramagnetic species with a facial geometry of the chloride ligands. The nitrogen donors of the tridentate LⁿR ligands complete the distorted octahedral coordination spheres of the complexes. Crystal data: [ReCl₃(L¹Et)] (1), monoclinic, C2/m, a = 16.088(3) Å, b = 9.980(2) Å, c = 12.829(2) Å, β = 91.384(3)°, Z = 4, D_calc = 1.967 g/cm^-3; [ReCl₃(L⁴Et)] (4), monoclinic, C2/c, a = 22.880(1) Å, b = 7.4926(4) Å, c = 22.560(1) Å, β = 94.186(1)°, Z = 8, D_calc = 2.001 g/cm^-3.
