Abstract

Single crystals of the new compound Pr3InSe6 have been obtained by direct reaction among Pr, Se, and In2Se3 powders at 950°C. The material crystallizes with four formula units in space group C5 2h - P21 c of the monoclinic system in a cell (at 123 K) of dimensions a = 4.109(1), b = 14.275(1), c = 17.891(2) Å, β = 103.27(1)°. The structure has been solved and refined from single-crystal X-ray data. The asymmetric unit contains three independent Pr atoms, two independent In atoms, and six independent Se atoms. Two of the crystallographically unique Pr atoms are in distorted bicapped trigonal prisms or distorted square antiprisms of Se atoms with PrSe interactions ranging from 2.970(2) to 3.281(2) Å while the other Pr atom is 7-coordinate in a greatly distorted monocapped octahedral environment with PrSe interactions ranging from 2.911(2) to 3.079(2) Å. Both independent In atoms are in distorted octahedra of Se atoms with InSe interactions ranging from 2.537(2) to 2.856(2) Å.
