Zusammenfassung: | <jats:p>While TiCl<jats:sub>4</jats:sub> and Na<jats:sub>2</jats:sub>S<jats:sub>4</jats:sub> react in in the presence of PPh<jats:sub>4</jats:sub>Cl in dichloromethane to yield (PPh<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>[TiSCl<jats:sub>4</jats:sub>]·2CH<jats:sub>2</jats:sub>Cl<jats:sub>2</jats:sub>, we obtained [Ti<jats:sub>4</jats:sub>O<jats:sub>6</jats:sub>(OSMe<jats:sub>2</jats:sub>)<jats:sub>12</jats:sub>]Cl<jats:sub>4·</jats:sub>5Me<jats:sub>2</jats:sub>SO · 1/2H<jats:sub>2</jats:sub>O (1) from the same reactants in dimethylsulfoxide. Compound 1 is only stable in the presence of dimethylsulfoxide. The crystal structure determination at 153 K shows the presence of cations having an adamantane-like Ti<jats:sub>4</jats:sub>O<jats:sub>6</jats:sub> <jats:sup>4+</jats:sup> skeleton with three Me<jats:sub>2</jats:sub>SO molecules coordinated to each Ti atom via their O atoms. Crystal data: monoclinic, P 2<jats:sub>1</jats:sub>/n, Z = 4, a = 1096.9, b = 3097, c = 2342.7 pm, β = 93.90° (at -120 °C; R = 0.087 % for 4098 reflections). In an attempt to produce the same compound only from TiCl<jats:sub>4</jats:sub> and Me<jats:sub>2</jats:sub>SO, [TiO(OSMe<jats:sub>2</jats:sub>)<jats:sub>5</jats:sub>]Cl<jats:sub>2</jats:sub> was obtained. Its cation has a rather short Ti=O bond (164.8 pm) and a distorted octahedral coordination of the titanium atom. The crystals are triclinic, P1̄, Z = 2, R = 0.050 for 2063 reflections measured at 153 K.</jats:p> |
