title: A new ring-like arrangement of vanadyl(IV) groups bridged by monodentate alkoxides: cyclo-decakis(μ-cyclohexylmethanolato)pentakis[oxidovanadium(IV)].
abstract: The pentanuclear title compound, [V(5)(C(7)H(13)O)(10)O(5)], has a metal-oxygen core that consists of five vanadyl(IV) centres bridged by the O atoms of cyclohexylmethanolate ligands. This particular ring topology is new to oxovanadium(IV) chemistry and resembles the structure proposed for [V(5)O(15)](5-) on the basis of (51)V NMR studies in aqueous solution. The bulky cyclohexylmethanolate ligands adopt chair-like conformations and project outwards from the central cyclic core. The title compound crystallizes in a centrosymmetric triclinic unit cell, which contains four independent but chemically identical molecules in the asymmetric unit. The crystal structure is devoid of any significant intermolecular interactions.
