Abstract

An organic molecule containing cobalt phosphate (denoted CoPO-GIS) which is isostructural with the zeolite gismondine has been synthesized under solvothermal conditions by using [Co(en)3]Cl3 and phosphoric acid as the reactants and ethylene glycol as the solvent. CoPO-GIS ((H3NCH2CH2NH3)0.5.CoPO4) crystallizes in the monoclinic space group C2/c with a = 14.744(3) A, b = 8.850(3) A, c = 10.062(3) A, beta = 131.609(19) degrees, and Z = 8. The structure consists of a 3-D network of strictly alternating CoO4 and PO4 tetrahedra interconnected by oxygen bridges, and the charge-balancing diprotonated ethylenediamine cations are highly ordered in the cages of the CoPO4 framework. CoPO-GIS is the only amine-containing cobalt phosphate with a known zeolite topology.
