New X-ray powder diffraction data for heterometallic complexes with unsaturated organic ligands Cp(CO)₂MnPt(μ-C=CHPh)(η²-dppm), [Cp(CO)₂MnCu(μ-C=CHPh)]₂(μ-Cl)₂, CpMnFe₂(μ₃-C=CHPh)(CO)₈ and η⁴-[Cp(CO)₂MnC(CO)CHPh]Fe(CO)₃(Cp=η⁵-C₅H₅;dppm=Ph₂PCH₂PPh₂)

Abstract

Four heterometallic carbonyl complexes: ( 1 ) Cp(CO) 2 MnPt( μ -C=CHPh)dppm) ( 2 ) [Cp(CO) 2 MnCu( μ -C=CHPh)( μ -Cl)] 2 , ( 3 ) CpMnFe 2 ( μ 3 -C=CHPh)(CO) 8 , and ( 4 ) η 4 -[Cp(CO) 2 MnC(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) Å, b =18.6092(14) Å, c =23.8117(18) Å, Z =8, space group Pbca. Monoclinic cell parameters found for complex ( 2 ) are a =11.5816(5) Å, b =7.9784(5) Å, c =16.7819(7) Å, β =105.460(2)°, Z =2, space group P2 1 ∕n. Orthorhombic cell parameters for complex ( 3 ) are a =13.5260(9) Å, b =15.1487(10) Å, c =10.3330(6) Å, Z =4, space group Pna 2 1 . Monoclinic cell parameters for complex ( 4 ) are a =10.3545(45) Å, b =8.0002(43) Å, c =21.8355(95) Å, 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.
