25 - 026Three-Dimensional Open-Framework Cobalt(II) Phosphates byNovel Routes. — The structures of the novel open-framework compounds(III) and (IV) are determined by single crystal XRD. (III) crystallizes in themonoclinic space group P21/c (Z = 4) and (IV) is orthorhombic (space groupP212121, Z = 4). The structures of both compounds are formed by alternatingCoO4 and PO4 tetrahedra. The connectivity leads to the formation of large16-membered channels in (III) and to 8-membered channels in the case of (IV).Strong hydrogen bonding involving the amine cations and framework oxygensis observed in both compounds. — (NATARAJAN, SRINIVASAN; NEERAJ,S.; CHOUDHURY, AMITAVA; RAO, C.
