Crystal Structure and Electronic Properties of New Compound ZrPtSe.

A new ternary nonstoichiometric ZrPtSe has been discovered as a part of effort to dope Zr into the layered transitional metal chalcogenide PtSe. With a new structure type (68), it is the first Pt-based ternary chalcogenide with group 4 elements (Ti, Zr, and Hf). The crystal structure adopts the orthorhombic space group with lattice parameters of = 15.
