Hydrothermal synthesis, crystal structure and characterization of LiCoP5O14·H2O: A new condensed layered penta phosphate crystals

A new family of condensed hydrated lithium cobalt penta phosphate (LiCoP5O14·H2O) crystals were synthesized by hydrothermal technique and characterized by X-ray diffraction method. The compound crystallizes in monoclinic system with space group P21/c and cell parameters a = 10.788(4) Å, b = 9.761(3) Å, c = 9.788(5) Å, β = 101.249(1) Å, Z = 4, exhibiting layer type polymeric structure. DTA study indicates that this compound has low thermal stability and magnetically frequency dependent paramagnetic behaviour.
