A two-dimensional supramolecular compound di-n-butyltin piperonylate, {(μ3-O)(μ2-OMe)(n-Bu2Sn)2[O2CAr(C2H4O)]}2 constructed by hydrogen bonds with a Sn4O4 ladder-like framework, was obtained by the microwave-assisted solvothermal reaction of di-n-butyltin oxide precursor with the piperonylic acid in methanol environments. The composite was characterized by elemental analysis and IR (1H,13C and119Sn) NMR spectra. The compound crystallizes in monoclinic system, space group P21/n with a = 13.3690(12), b = 14.1442(14), c = 16.4022(16) Å, β = 10...
