By hydrothermal reaction of In{sub 2}O{sub 3} with H{sub 2}C{sub 2}O{sub 4}.2H{sub 2}O in the presence of H{sub 3}BO{sub 3} at 155 deg. C, an open-framework three-dimensional indium oxalate of formula [In(OH)(C{sub 2}O{sub 4})(H{sub 2}O)]{sub 3}.H{sub 2}O (1) has been obtained. The compound crystallizes in the trigonal system, space group R3c with a=18.668(3)A, c=7.953(2)A, V=2400.3(7)A{sup 3}, Z=6, R{sub 1}=0.0352 at 298K. The small pores in 1 are filled with water molecules. It loses its filled water at about 180 deg. C without the change of structure, then the bounded water at 260 deg. C, and completely decompounds at 324 deg. C. The residue is confirmed to be In{sub 2}O{sub 3}.
