KSrPtZn crystallizes in the trigonal R3m space group. K(1) is bonded to one Sr(1) and three equivalent Pt(1) atoms to form KSrPt3 trigonal pyramids that share  a cornercorner with one Pt(1)K3SrZn trigonal bipyramid and corners with six equivalent K(1)SrPt3 trigonal pyramids. The K(1)-Sr(1) bond length is 1.99 Å. All K(1)-Pt(1) bond lengths are 3.03 Å. Sr(1) is bonded in a 1-coordinate geometry to one K(1) and one Pt(1) atom. The Sr(1)-Pt(1) bond length is 1.99 Å. Pt(1) is bonded to three equivalent K(1), one Sr(1), and one Zn(1) atom to form distorted PtK3SrZn trigonal bipyramids that share corners with six equivalent Pt(1)K3SrZn trigonal bipyramids and  a cornercorner with one K(1)SrPt3 trigonal pyramid. The Pt(1)-Zn(1) bond length is 1.99 Å. Zn(1) is bonded in a distorted single-bond geometry to one Pt(1) atom.
