Article abstract of DOI:10.1007/BF01156078

The crystal and molecular structure of (C6H5)3SnOCOCCH2CH3 has been determined by a single crystal X-ray diffraction study.The crystal is monoclinic with space group P2₁/c, a = 11.902(3), b = 10.104(4), c = 16.721(2) Angstroem, β = 97.56(1) deg, V = 1930.4 Angstroem³, Z = 4 and D_c = 1.495 g/cm³, F(0,0,0) = 872, λ(Cu Kα) = 1.5418 Angstroem.The structure was solved by the heavy-atom method and refined by full-matrix least-squares procedures to an R factor of 0.060 based on 2157 independent reflections.The results showed that the Sn-O bond distance is 2.064(4) Angstroem.The average Sn-C bond distance is 2.126 Angstroem.There is a weak coordination through the O of the CO group of the methacrylate residue (Sn-O(2) 2.774(5) Angstroem) except for four normal coordinations.The coordination number at the Sn⁴⁺ is 5.
