A new tetranuclear organotin carboxylate {[(n-Bu2SnO)(2)L](2)}(n) (complex 1) was synthesized by the reaction of di-n-butyltin oxide with (p-carboxymethoxy-phenoxy) acetic acid (LH2) and characterized by elemental analyses: IR, UV-visible, H-1, C-13, Sn-119 NMR spectroscopy and single crystal X-ray study. X-ray crystallography diffraction data revealed that the complex 1 was polymeric fashion with a chain structure containing a ladder-like tetranuclear organo-oxotin cluster. In the complex 1, the ligand LH2 is coordinated to the central tin(IV) atoms via the carboxylato-O atoms. The tetranuclear tin system is formed by the bridges through the carbonyl oxygen atom of the carboxylate moieties and making the tin atom of pentacoordinated in distorted trigonal bipyramidal geometry. Single crystal X-ray data indicate that the complex 1 crystallized in the cubic system with the space group C-2/c.
