摘      要：The title ladder organotin carboxylate,{[（C6H5CH2）2Sn]4（p-NH2C6H4-COO）2O2（OCH3）2}·0.5H2O 1,has been synthesized and structurally characterized by elemental analyses,IR and single-crystal X-ray diffraction *** 1 is located across on an inversion center and displays a Sn4O4 ladder-like structure with a one-dimensional supramolecular chain through C-H…π *** the asymmetric unit two Sn（Ⅳ） atoms assume similar trigonal bipyramidal coordination *** aminobenzoate groups coordinate to the terminal Sn（Ⅳ） *** deprotonated methanol molecule bridges two independent Sn（Ⅳ） atoms.A half of lattice water molecule is disorderly filled in the cavity formed by Sn（Ⅳ） complexes.
