چکیده
The title compound, [Sn(C4H9)2(C2O4)] n , an unexpected side product in the reaction of di-tert-butyl-tin(IV) oxide with nitric acid, represents the first diorganotin(IV) oxalate to be structurally characterized. The Sn(IV) atom of the one-dimensional coordination polymer is located on a mirror plane and is coordinated by two chelating oxalate ions with two rather different Sn-O bond lengths of 2.150 (1) and 2.425 (1) Å, and two t-butyl groups with Sn-C bond lengths of 2.186 (2) and 2.190 (2) Å. The coordination polyhedron around the Sn(IV) atom is a distorted tetra-gonal disphenoid. The centrosymmetric oxalate ion also has an asymmetric coordination geometry, as reflected by the two slightly different C-O bond lengths of 1.242 (2) and 1.269 (2) Å. The chains of the polymer propagate along the b-axis direction. Only van der Waals inter-actions are observed between the chains.

The title compound, [Sn(C(6)H(5))(3)(C(17)H(25)O(3)S)](n), comprises two symmetry-independent five-coordinated triphenyl-tin mol-ecules which are linked by carboxyl-ate bridges into a polymeric chain. The Sn(IV) atom is in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The presence of two bulky tert-butyl groups on the benzene ring prevents any hydrogen-bonding inter-actions involv...

The structure of the title compound, {(NH4)2[Cu(C2O4)2]} n , at 100 K has monoclinic (P21/c) symmetry with the CuII atom on an inversion center. The compound has a polymeric structure due to long Cu⋯O inter-actions which create [Cu(C2O4)2] chains along the a axis. The structure also displays inter-molecular N-H⋯O hydrogen bonding, which links these chains into a three-dimensional network.
