The Sn(IV) atom in the title carboxyl-ate-bridged polymer, Sn(C(7)H(7))(3)(C(9)H(7)O(2)), 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.
在标题中的羧酸盐桥联聚合物[Sn(C₇H₇)₃(C₉H₇O₂)]ₙ中，Sn(IV)原子呈反式-C₃SnO₂三角双锥几何构型（平均共价Sn - O = 2.167 Å，平均配位Sn - O = 2.361 Å，平均O - Sn - O = 169.6°）。该聚合物沿b轴以螺旋链形式延伸，重复距离为b轴长度的一半。不对称单元中有四个独立的化学式单元；其中两个相对于另外两个围绕一个假反演中心排列，使得空间群模拟一个有心空间群。
