Synthesis and Crystal Structure of a Novel Monomeric Di-butyltin Dicarboxylate: ⁿBu₂Sn〔O₂CCH₂CH（4-ClC₆H₄）Ge（OCH₂CH₂）₃N〕₂·H₂O

nBu 2Sn O 2CCH 2CH(4 ClC 6H 4)Ge(OCH 2CH 2) 3N 2·H 2O( M r =1053.66) is an air stable compound which crystallizes in the monoclinic space group C2/c with a=21.182(5), b=12.174(3), c=17.108(4) , β=99.59(2)°, V=4350(3) 3, Z=4, F(000)=2104, μ =2.104 mm -1 . The refinement of structure with I≥3σ(I) for 1819 reflections converged at R =0.045. The coordination geometry around the Sn atom is best described as an askew pentagonal bipyramid, in which four carboxylate oxygen atoms ( Sn(1)-O(5), Sn(1)-O(5a)=2.099 and Sn(1)-O(4), Sn(1)-O(4a)=2.158 ) and an oxygen atom from an aqua ligand comprise the pentagonal plane, with two butyl groups occupying axial positions.
