Crystal and Molecular Structures of C7H7Mo(CO)2Sn(C6H5)2Cl (I) and C7H7Mo(CO)2SnC6H5Cl2 (II)The structures of the title compounds I and II were solved by x-ray methods using least squares refinement. I and II both crystallize in the monoclinic space group C2h5 -P21/n with a = 8.479 Å, b = 18.295 Å, c = 12.795 Å, β = 90.751° and a = 6.937 Å, b = 14.883 Å, c = 19.086 Å, β = 90.585° respectively. For both Z is 4. In I and II there exists a molybdenum-tin bond; the coordination of molybdenum is approximately tetrahedral. As ligands serve two carbonyl groups, the cycloheptatrienyl ring, the Sn(C6H5)2Cl and the Sn(C6H5)Cl2 group respectively.
Notes:
Die Strukturen der Titelverbindungen I und II wurden röntgenographisch bestimmt und nach der Methode der kleinsten Quadrate verfeinert. I und II kristallisieren monoklin in der Raumgruppe C2h5 -P21/n mit a = 8,479 Å, b = 18,295Å. c = 12,795 Å, β = 90,751° bzw. a = 6,937 Å, b = 14,883 Å, c = 19,086 Å, β = 90,585°. Z beträgt jeweils 4. In I und II liegt eine Molybdän-Zinn-Bindung vor; das Molybdän in I und II ist angenähert tetraedrisch von zwei CO-Gruppen, einem Cyclohepatrienylring und den Sn(C6H5)2Cl bzw. Sn(C6H5)Cl2 Liganden umgeben.
