In the title polymeric coordination compound, Sn(CH(3))(3)(C(20)H(12)O(4)P), the Sn atom exhibits a distorted trigonal-bipyramidal coordination geometry with the phosphate O atoms of the 1,1'-binaphthyl-2,2'-diyl phospho-nate ligands in axial positions and equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 1,1'-binaphthyl-2,2'-diyl phospho-nate ligand, forming a one-dimensional chain structure parallel to the b axis.
在标题聚合物配位化合物Sn(CH(3))(3)(C(20)H(12)O(4)P)中,Sn原子呈现出扭曲的三角双锥配位几何构型,其中1,1'-联萘-2,2'-二基膦酸酯配体的磷酸O原子处于轴向位置,三个甲基占据赤道位置。相邻的Sn原子通过与每个1,1'-联萘-2,2'-二基膦酸酯配体的两个O原子配位而桥连,形成平行于b轴的一维链状结构。
