Abstract

Titanium(IV) chloride was reacted with a slight excess of barium pentafluorophenoxide in tetrahydrofuran (THF) solution. After filtration and solvent evaporation, the resulting orange crystalline material was obtained. The product was recrystallized by preparing a concentrated solution in THF at room temperature, followed by cooling to 253 K. The supernatant solution was decanted using a pipet, and the crystals were dried by allowing the solvent to evaporate in the atmosphere of a glovebox. It was possible to obtain good-quality X-ray data at 100 K on a crystal, namely, tetrakis(pentafluorophenoxido-κO)bis(tetrahydrofuran-κO)titanium(IV), [Ti(C₆F₅O)₄(C₄H₈O)₂], having monoclinic (P2₁/n) symmetry. This compound adopts a solid-state structure in which the titanium(IV) ions have a distorted octahedral coordination environment with two coordinated THF molecules occupying cis positions.

四氧基（五氟苯氧基）二氧基（四氢呋喃）钛的结构（IV）。

氯化钛（IV）在四氢呋喃（THF）溶液中与略过量的五氟苯氧化钡反应。经过过滤和溶剂蒸发，得到橙色结晶材料。在室温下制备THF浓溶液，然后冷却至253 K，再结晶。用移液管除去上清溶液，并通过让溶剂在手套箱的空气中蒸发来干燥晶体。可以在100 K下获得高质量的x射线数据，即具有单斜（P21/n）对称性的四基-（五氟-苯氧基-κ o）二基-（四氢呋喃-κ o）钛（IV）， [Ti(c6f50)4(c4h80)2]晶体。该化合物采用固体结构，其中钛（IV）离子具有扭曲的八面体配位环境，两个配位的THF分子占据顺式位置。
