A novel type of heteropolyoxoanion precursors {[Ca(H2O)]6[P4M6O34]2}12− (M = WVI, MoVI) constructed by two [P4M6O34]12− subunits via a rare hexa-calcium cluster†
Abstract
A novel type of heteropolyoxoanion (HPOA) precursors {[Ca (H2O)]6[P4M6O34]2}12− [M = WVI (1), MoVI (2)] has been synthesized and structurally characterized, which represents the rare membership of the HPOA family constituted by two early-transition-metal clusters ([P4M6O34]12−) and a main-group metal cluster of high nuclearity ([Ca6]12+).
