摘要：

Reaction between bis(chlorodiphenylstanyl)methane and the sodium salt of 2-hydroxypyridine (pyONa) in the molar ratio of 1:2 provides the organotin hydroxide derivative [Ph-2(pyO)SnCH2Sn(OH)Ph-2](2) (1) (where pyO = anion of 2-hydroxypyridine), while reaction of bis(dibromophenylstanyl) methane with the sodium salt of pyrimidine-2-thione (pmtNa) in molar ratio of 1:4 gives the corresponding organotin thiolate derivative, as its toluene solvate [BrPh(pmt)Sn](2)CH(2)center dot C7H8 (2) (where pmt = anion of pyrimidine-2-thione). Both compounds were characterized by single crystal X-ray diffraction analysis and contain five-coordinate tin atoms. Compound 1 is a centrosymmetric head-to-tail dimmer with almost symmetrical Sn(1)-O(H)-Sn(2A) bridges. (c) 2005 Elsevier B.V. All rights reserved.
