Ca Ge Pt Pt
CaPt2Ge crystallizes in the monoclinic Cm space group. Ca(1) is bonded to four equivalent Pt(2) and one Ge(1) atom to form a mixture of distorted edge and corner-sharing CaGePt4 square pyramids. There are a spread of Ca(1)-Pt(2) bond distances ranging from 2.08-2.32 Å. The Ca(1)-Ge(1) bond length is 1.98 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 8-coordinate geometry to one Pt(2), four equivalent Pt(1), and three equivalent Ge(1) atoms. The Pt(1)-Pt(2) bond length is 2.67 Å. All Pt(1)-Pt(1) bond lengths are 3.06 Å. There is one shorter (3.15 Å) and two longer (3.23 Å) Pt(1)-Ge(1) bond lengths. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to four equivalent Ca(1) and one Pt(1) atom. Ge(1) is bonded in a single-bond geometry to one Ca(1) and three equivalent Pt(1) atoms.
