چکیده
The Sn(IV) atom in the title carboxyl-ate-bridged polymer, [Sn(C(7)H(7))(3)(C(9)H(7)O(2))](n), exists in a trans-C(3)SnO(2) trigonal-bipyramidal geometry (average covalent Sn-O = 2.167 Å, average dative Sn-O = 2.361 Å and average O-Sn-O = 169.6°). The polymer propagates as a helical chain along the b axis with a repeat distance that is half the b-axial length. There are four independent formula units in the asymmetric unit; two are disposed about a false center of inversion with respect to the other two so that the space group emulates a centric space group.
