Abstract

A new monohydrate of lithium perrhenate LiReO4·H2O was prepared by dehydration of LiReO4·1.5H2O at room temperature. The single crystals of LiReO4·H2O were obtained by crystallisation from the isoamyl acetate solution of LiReO4·1.5H2O. The structure of monohydrate (a = 5.6674(4), b = 10.771(1), c = 7.4738(7) Å, β = 102.422(7)°, R1 = 0.0414, space group P21/a, Z = 4) is built up from LiO3(H2O)2 trigonal bipyramids and ReO4 tetrahedra sharing common edges and corners inside the layers. The layers are connected together by hydrogen bonds. The relationships between the structures of sesquihydrate, monohydrate and anhydrous LiReO4 are discussed.
