K Y Y Y Y Pt
KY4Pt crystallizes in the trigonal R3m space group. K(1) is bonded in a 15-coordinate geometry to three equivalent Y(2), nine equivalent Y(1), and three equivalent Pt(1) atoms. All K(1)-Y(2) bond lengths are 3.76 Å. There are six shorter (3.99 Å) and three longer (4.20 Å) K(1)-Y(1) bond lengths. All K(1)-Pt(1) bond lengths are 3.81 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 3-coordinate geometry to three equivalent K(1), one Y(2), two equivalent Y(1), and one Pt(1) atom. The Y(1)-Y(2) bond length is 2.79 Å. Both Y(1)-Y(1) bond lengths are 1.61 Å. The Y(1)-Pt(1) bond length is 3.13 Å. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to three equivalent K(1), three equivalent Y(1), and three equivalent Pt(1) atoms. All Y(2)-Pt(1) bond lengths are 3.93 Å. Pt(1) is bonded in a 6-coordinate geometry to three equivalent K(1), three equivalent Y(1), and three equivalent Y(2) atoms.
