Abstract
The crystal and molecular structure of dicarbonyl-π-cyclopentadienyl[dichloro(phenyl)stannyl]iron has been determined by single-crystal X-ray diffraction analysis using the intensities of 995 reflections measured by counter diffractometry. Crystals are monoclinic, a= 14·940(2), b= 8·503(1), c= 12·582(2)Å, β= 102·98(1)°, Z= 4, space group P21/c. The structure was determined by the heavy-atom method and parameters were refined by block-diagonal least-squares methods to R 0·041. Individual anisotropic thermal parameters were used and no account was taken of hydrogen atoms. The molecule contains a short Sn–Fe σ-bond of length 2·467(2)Å. Valence angles around the tin atom are : Fe–Sn–Cl 110·1(1) and 112·9(1), Fe–Sn–C 129·7(3), Cl–Sn–Cl 99·1 (1), and Cl–Sn–C 99·9(4) and 100·5(4)°. Mean bond distances are : Sn–Cl 2·385(3), Sn–C 2·13(1), Fe–C(ring) 2·09(2), Fe–C(carbonyl) 1·75(1), and C–O, 1·16(2)Å. There are no abnormally short non-bonded contacts, either inter- or intra-molecular.Keywords
