New X-ray powder diffraction data for heterometallic complexes with unsaturated organic ligands Cp(CO)_2MnPt(μ-C=CHPh)(η~2-dppm), [Cp(CO)_2MnCu(μ-C=CHPh)]_2(μ-Cl)_2, CpMnFe_2(μ_3-C=CHPh)(CO)_8 and η~4-[Cp(CO)_2MnC(CO)CHPh]Fe(CO)_3(Cp= η~5-C_5H_5;

摘要

Four heterometallic carbonyl complexes: (1) Cp(CO)_2MnPt(μ-C=CHPh)(dppm) (2) [Cp(CO)_2MnCu(μ-C=CHPh)(μ-Cl)]_2, (3) CpMnFe_2(μ_3-C=CHPh)(CO)_8, and (4) η~4 -[Cp(CO)_2MnC(CO)CHPh]Fe(CO)_3 have been studied by X-ray powder diffraction and their unit cell parameters are reported. Orthorhombic cell parameters for complex (1) are a = 18.5719(14) A, b= 18.6092(14) A, c = 23.8117(18) A, Z=8, space group Pbca. Monoclinic cell parameters found for complex (2) are a = 11.5816(5) A, b = 7.9784(5) A, c= 16.7819(7) A, β = 105.460(2)°, Z=2, space group P2_1. Orthorhombic cell parameters for complex (3) are a = 13.5260(9) A, b=15.1487(10) A, c= 10.3330(6) A, Z=4, space group Pna2_1. Monoclinic cell parameters for complex (4) are a = 10.3545(45) A, b = 8.0002(43) A, c = 21.8355(95) A, β = 102.89(2), Z=4, space group P2_1/c. Parameters found for complexes (1-4) are in good agreement with those obtained from single crystal X-ray diffractometry.
