  The reactions of (Ph4P) [VO2Cl2] in various alcohols yield complexes of the type (Ph4P)(2)[(VO)(2)Cl-4(OR)(2)] (R =-CH3 (1),-CH2CH2Cl (2)). Similarly, the reaction of (BzPh(3)P)[VO2Cl2] with tris(hydroxymethyl) ethane yields [(VO)(2)Cl-2(MeC(CH2OH) (CH2O)(2)}(2)]. 2BzPh(3)PCl . 2CH(3)OH (3 . 2BzPh(3)PCl . 2CH(3)OH). The molecular anions of complexes 1 and 2 consist of binuclear units of edge-sharing V(IV) square pyramids. The alkoxy groups bridge the two V(V) sites and the V=O} groups adopt the anti-orientation with respect to the (V2O2} rhombus of the bridging unit. In contrast, the neutral [(VO)(2)Cl-2(MeC(CH2OH) (CH2O)(2))(2)] consists of the edge-sharing V(V) octahedra. The tridentate ligands each provide one alkoxy oxygen adopting a bridging mode between V(V) sites, an alkoxy oxygen as a terminal ligand to one V(V) site and an alcohol oxygen donor as a terminal ligand to the other V(V) site. The terminal ore-groups occupy positions approximately coplanar to the (V2O2} rhombus of the bridging unit.
