Ca Ca Ca Ca Zn Ru
Ca4RuZn crystallizes in the trigonal R3m space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 2-coordinate geometry to one Ca(2), two equivalent Ca(1), one Ru(1), and two equivalent Zn(1) atoms. The Ca(1)-Ca(2) bond length is 1.77 Å. Both Ca(1)-Ca(1) bond lengths are 1.02 Å. The Ca(1)-Ru(1) bond length is 2.41 Å. Both Ca(1)-Zn(1) bond lengths are 3.42 Å. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to three equivalent Ca(1), three equivalent Ru(1), and three equivalent Zn(1) atoms. All Ca(2)-Ru(1) bond lengths are 3.71 Å. All Ca(2)-Zn(1) bond lengths are 3.65 Å. Ru(1) is bonded in a 6-coordinate geometry to three equivalent Ca(1) and three equivalent Ca(2) atoms. Zn(1) is bonded in a 9-coordinate geometry to three equivalent Ca(2) and six equivalent Ca(1) atoms.
