Synthesis, Characterization and Crystal Structure of a Novel One-Dimensional Supramolecular Dimethyltin (IV) Compound

Abstract

A novel one-dimensional (1D) supramolecular dimethyltin compound of (Me2SnO)2(Me2SnOCH3)(O2CCH2SC4H3N2-2,6)[Me2Sn(O2CCH2SC4H3N2-2,6)2]·CH3OH was prepared by the reaction of (CH3)2SnCl2 with (2-pyrimidylthio)acetic acid with CH3ONa as a base. The title compound contained four different tin atom environments. Among them, Sn(1) and Sn(2) were both five-coordinate with distorted trigonal bipyramidal geometries, Sn(3) was six-coordinate with a distorted octahedral geometry and Sn(4) was seven-coordinate with pentagonal bipyramidal geometry. Meanwhile, the compound was stabilized in a 1D infinite chain by intermolecular Sn–O bonds.
