K2PtSe2 crystallizes in the orthorhombic Immm space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1) and six equivalent Se(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Se(1) atoms. Se(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Pt(1) atoms.
K2PtSe2 crystallizes in the orthorhombic Immm space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Pt(1) and six equivalent Se(1) atoms. Both K(1)-Pt(1) bond lengths are 3.47 Å. There are two shorter (3.34 Å) and four longer (3.40 Å) K(1)-Se(1) bond lengths. Pt(1) is bonded in a 8-coordinate geometry to four equivalent K(1) and four equivalent Se(1) atoms. All Pt(1)-Se(1) bond lengths are 2.49 Å. Se(1) is bonded in a 8-coordinate geometry to six equivalent K(1) and two equivalent Pt(1) atoms.
