K Zn Co Co
KCo2Zn crystallizes in the triclinic P1 space group. K(1) is bonded in a distorted single-bond geometry to one Co(2) and one Zn(1) atom. The K(1)-Co(2) bond length is 3.56 Å. The K(1)-Zn(1) bond length is 2.32 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 2-coordinate geometry to four equivalent Co(2) atoms. There are a spread of Co(1)-Co(2) bond distances ranging from 1.60-2.76 Å. In the second Co site, Co(2) is bonded in a 6-coordinate geometry to one K(1), four equivalent Co(1), and one Zn(1) atom. The Co(2)-Zn(1) bond length is 2.83 Å. Zn(1) is bonded in a distorted single-bond geometry to one K(1) and one Co(2) atom.
