The iron potassium diarsenate KFeAs{sub 2}O{sub 7} structural, electric and magnetic behaviors

Crystals of a new potassium iron (III) diarsenate (KFeAs{sub 2}O{sub 7}) have been grown and characterized by single crystal X-ray diffraction. It crystallizes in the triclinic space group P1-bar, with a=7.662(1) A, b=8.402(2) A, c=10.100(3) A, {alpha}=90.42(3){sup o}, {beta}=89.74(2){sup o}, {gamma...
