| Abstract: | (C4N2H12)CrO(H1.5PO4)2·H2O has been synthesized hydrothermally using piperazine as organic template. Its crystal structure was solved ab initio using synchrotron powder X-ray diffraction data monoclinic, a = 16.9649(4) Å, b = 9.8609(2) Å, c = 7.14375(14) Å, and β = 94.896(3)°, space group P21/a, Z = 4]. 1D structure is composed by isolated infinite anionic chains CrO(H1.5PO4)2]n (vertex-sharing {CrO6} octahedra joined by phosphate moieties). Their 2D plate-like morphology is propitiated by a very strong inter-chain interaction (P–O···H···O–P symmetric hydrogen bonds). KAS isoconversional method was applied to determine the activation energy for both thermal and thermo-oxidative decomposition of (C4N2H12)CrO(H1.5PO4)2·H2O. |
