K Ca Pt Rh
KCaRhPt is Zintl Phase-derived structured and crystallizes in the trigonal R3m space group. K(1) is bonded in a 14-coordinate geometry to four equivalent Ca(1), six equivalent Rh(1), and four equivalent Pt(1) atoms. There are three shorter (3.00 Å) and one longer (3.09 Å) K(1)-Ca(1) bond length. There are three shorter (3.41 Å) and three longer (3.57 Å) K(1)-Rh(1) bond lengths. There is one shorter (2.82 Å) and three longer (3.10 Å) K(1)-Pt(1) bond lengths. Ca(1) is bonded in a 14-coordinate geometry to four equivalent K(1), four equivalent Rh(1), and six equivalent Pt(1) atoms. There are three shorter (3.00 Å) and one longer (3.09 Å) Ca(1)-Rh(1) bond length. There are three shorter (3.41 Å) and three longer (3.57 Å) Ca(1)-Pt(1) bond lengths. Rh(1) is bonded to six equivalent K(1) and four equivalent Ca(1) atoms to form distorted RhK6Ca4 tetrahedra that share corners with six equivalent Rh(1)K6Ca4 tetrahedra, edges with twelve equivalent Pt(1)K4Ca6 tetrahedra, faces with four equivalent Pt(1)K4Ca6 tetrahedra, and faces with twelve equivalent Rh(1)K6Ca4 tetrahedra. Pt(1) is bonded to four equivalent K(1) and six equivalent Ca(1) atoms to form distorted PtK4Ca6 tetrahedra that share corners with six equivalent Pt(1)K4Ca6 tetrahedra, edges with twelve equivalent Rh(1)K6Ca4 tetrahedra, faces with four equivalent Rh(1)K6Ca4 tetrahedra, and faces with twelve equivalent Pt(1)K4Ca6 tetrahedra.
