Single crystals of the ternary indide CeNiIn2 were synthesized from an indium flux. An arc-melted button of the starting composition CeNiIn2 was annealed in a zirconia crucible with a slight excess of indium at 1200 K followed by slow cooling (5 K/h) to 870 K. The new indide has been investigated by X-ray diffraction on powders and single crystals: PrNiIn2 type, Cmcm, a = 440.78(4), b = 1834.3(1), c = 2178.8(2) pm, wR2= 0.0753 for 1471 F2 values and 66 variable parameters. The structure contains three crystallographically independent nickel positions which have a distorted trigonal prismatic coordination. The CeNiIn2 structure is related to the MgCuAl2 structure by chemical twinning. The shortest interatomic distances occur for Ni-In and In-In contacts. The nickel and indium atoms form a complex three-dimensional [NiIn2] network in which the cerium atoms fill distorted pentagonal channels. Magnetic susceptibility measurements indicate Curie-Weiss behavior with an experimental magnetic moment of 2.44(3) μB/Ce atom. At 3.4(3) K CeNiIn2 orders ferro- or ferrimagnetically. The experimental saturation magnetization at 2K and 5.5 T is 0.95(2) μB/Ce.
