A novel organooxotin complex of di-mu-oxygen and di-mu-hydroxyl bridged tetra(bisbutyltin) bis(pyridine-4-carboxylate) has been synthesized by the reaction of n-Bu2SnO with pyridine-4-carboxylic acid and characterized by IR, H-1 NMR spectra and elemental analysis. The crystal structure has been determined by X-ray diffraction. It crystallizes in the monoclinic, space group P2(1)/n with a=1.306 5 (3) nm, b=10314 5 (2) nm, c=1.660 8 (3) nm, beta= 96.180(5)degrees, V=2.835 7(9) nm(3), Z=4, D-c =1.454 g.cm(-3), mu(Mo K alpha)=1.784 mm(-1), F(000)=1 248, R-1=0.0449, wR(2) = 0.124 1 (I>2 sigma(I) ob...
