(CNH)CrO(HPO)·HO 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 P2/ a, Z = 4]. 1D structure is composed by isolated infinite anionic chains [CrO(HPO)] (vertex-sharing {CrO} 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 (CNH)CrO(HPO)·HO. [ABSTRACT FROM AUTHOR]
