Abstract

The title compound, [Ti(C19H23NO2)2]·1.5C7H8, crystallizes with one titanium complex mol-ecule per asymmetric unit together with one and a half toluene mol-ecules. The Ti(IV) atom is coordinated by two fully deprotonated O,N,O'-tridentate phen-oxy-amine ligands in a distorted octa-hedral environment. Within this arrangement the O atoms occupy the equatorial sites and the N atoms the axial sites. One of the toluene mol-ecules is disordered over two sets of sites in a 0.628 (18):0.372 (18) ratio.

摘要

标题化合物[Ti(C₁₉H₂₃NO₂)₂]·1.5C₇H₈，每个不对称单元包含一个钛配合物分子以及一个半甲苯分子。Ti(IV)原子在扭曲的八面体环境中由两个完全去质子化的O,N,O'-三齿苯氧基胺配体配位。在这种排列中，O原子占据赤道位置，N原子占据轴向位置。其中一个甲苯分子在两组位置上无序排列，比例为0.628 (18):0.372 (18)。
