Abstract

The title compound was prepared from the elements by a reaction in an are melting furnace and subsequent annealing at 970 K. Nd5Ni6In11 crystallizes with the orthorhombic Pr5Ni6In11-type structure: Cmmm, a = 1455.9(3)pm, b =53.3(3)pm, c = 438.3(1) pm, V = 0.9274(2) nm(3), wR(2), = 0.0551, 1086 F-2values, and 42 variables. The structure of Nd5Ni6In11 is built up from a complex three-dimensionally infinite [Ni6In11] polyanionic network in which the neodymium atoms occupy pentagonal and hexagonal channels. Magnetic susceptibility measurements indicate Curie-Weiss behavior above 150 K with an experimental magnetic moment of 3.60(5) mu(B)/Nd and a paramagnetic Curie temperature of -18(1) K. Antiferromagnetic ordering is detected at T-N = 11.4(1) K. Field- and temperature-dependent magnetization data indicate a complex magnetic phase diagram with spin reorientations into three antiferro- and one ferrimagnetic phase. The magnetic data are supported by specific heatmeasurements. Nd5Ni6In11 is a metallic conductor with a specific resistivity of 120 mu Omega cm at room temperature. (C) 1999 Academic Press.
