The first organo-templated cobalt phosphate with a zeolite topology

An organic molecule containing cobalt phosphate (denoted CoPO-GIS) which is isostructural with the zeolite gismondine has been synthesized under solvo thermal conditions by using [Co(en)(3)]Cl-3 and phosphoric acid as the reac tants and ethylene glycol as the solvent. CoPO-GIS ((H3NCH2CH2NH3)(0.5). Co PO4) crystallizes ill the monoclinic space group C2/c with a = 14.744(3) An gstrom, b = 8.850(3) Angstrom, c = 10.062(3) Angstrom, beta = 131.609(19)de grees, and Z = 8. The structure consists of a 3-D network of strictly alter nating CoO4 and PO4 tetrahedra interconnected by oxygen bridges, and the ch arge-balancing diprotonated ethylenediamine cations are highly ordered in t he cages of the CoPO4 framework. CoPO-GIS is the only amine-containing coba lt: phosphate with a known zeolite topology.
