K K Zn Mo
K2MoZn crystallizes in the triclinic P1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a single-bond geometry to one Mo(1) and two equivalent Zn(1) atoms. The K(1)-Mo(1) bond length is 1.69 Å. There is one shorter (2.99 Å) and one longer (3.62 Å) K(1)-Zn(1) bond length. In the second K site, K(2) is bonded in a single-bond geometry to one Mo(1) and two equivalent Zn(1) atoms. The K(2)-Mo(1) bond length is 1.76 Å. There is one shorter (3.37 Å) and one longer (3.60 Å) K(2)-Zn(1) bond length. Mo(1) is bonded in a distorted L-shaped geometry to one K(1), one K(2), and one Zn(1) atom. The Mo(1)-Zn(1) bond length is 2.28 Å. Zn(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Mo(1) atom.
