Abstract

In the title four-coordinate complex, [Ti(C(2)H(6)N)(2)(C(31)H(28)O(4))], two symmetry-independent mol-ecules are present in the asymmetric unit. The Ti(IV) atom displays a distorted tetra-hedral geometry, with Ti-O bond lengths ranging from 1.805 (3) to 1.830 (3) Å and O-Ti-O ligand bite angles of 100.16 (12) and 101.36 (12)°. The short Ti-N bond distances, ranging from 1.877 (4) to 1.905 (4) Å, indicate strong bonding between the Ti(IV) atom and the dimethyl-amide ligands.

摘要

在标题化合物四配位配合物[Ti(C₂H₆N)₂(C₃₁H₂₈O₄)]中，不对称单元中存在两个对称独立的分子。Ti(IV)原子呈现出扭曲的四面体几何构型，Ti - O键长范围为1.805(3)至1.830(3) Å，O - Ti - O配体夹角为100.16(12)°和101.36(12)°。短的Ti - N键距范围为1.877(4)至1.905(4) Å，表明Ti(IV)原子与二甲基酰胺配体之间存在强键合。
