摘要：
AgFeP2O7 has been synthesized by flux crystallization and characterized by single crystal and powder X-ray diffraction (sp gr. P2(1)/c, a=7.3298(2), b=7 9702(2), c=9.5653(2) angstrom, beta=111 842(1)degrees, V=518 68(2)angstrom(3)) and FTIR-spectroscopy The structure is composed of Isolated iron octahedra and phosphate tetrahedra interconnected into 3D network with hexagonal channels, where silver counterions are located The magnetic behavior of the compound approaches the Curie-Weiss equation with a Weiss constant 0= - 1659 K indicating strong antiferromagnetic interaction between iron(III) ions (C) 2010 Elsevier Inc All rights reserved
