摘要

New lithium copper(II) pyrophosphate, Li₂CuP₂O₇ crystals were synthesized by the hydrothermal technique at moderate temperature and pressure conditions. The as-synthesized compound was characterized by DTA/TGA, infrared radiation, single crystal XRD and magnetic susceptibility measurement. The compound has crystallized in monoclinic system with C2/c space group and cell parameters a = 15.3360(14) Å, b = 4.8733(13) Å, β = 114.8(1)°, V = 585.2(2) Å, having tunnel type of cavities in the structure. Thermal behaviour and structural coordination of the prepared materials were investigated, respectively, using DTA/TGA and FTIR measurements. Magnetic results have revealed; it is a frequency and temperature dependent prospective paramagnetic materials.
