Transparent single crystals of AgNiF 3 up to 3 mm on an edge have been grown by slow cooling from AgF flux. The crystals are tetragonal, space group D 6 4 -p4 2 2 1 2, with cell constants a = 5.56 A and c = 7.86 A . The material has an optical absorption spectrum typical of divalent nickel in octahedral coordination with fluoride ions. A noncollinear antiferromagnetic transition at 197°K is observed.
