Abstract

A new barium nickel phosphide BaNi9P5 was synthesized in a tin flux. Single crystal X-ray methods revealed that the material has hexagonal Laue symmetry with unit cell dimensions a = 6.5359(9) Å and c = 10.854(3) Å. The structure was refined in the space group P63 mmc to an R value of 2.3%. The structure is best described as hexagonal layers of Ba atoms with each Ba atom surrounded by Ni18P12 cages. The crystals have a silvery luster, and grow in an equidimensional, faceted habit. Magnetic measurements show temperature-independent Pauli paramagnetism, suggesting that BaNi9P5 is a metal.
