K K K K Mo Os
MoKK3Os is alpha As structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three K3Os clusters and three MoK clusters. In each K3Os cluster, K(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The K(1)-Os(1) bond length is 2.53 Å. Os(1) is bonded in a trigonal planar geometry to three equivalent K(1) atoms. In each MoK cluster, K(2) is bonded in a single-bond geometry to one Mo(1) atom. The K(2)-Mo(1) bond length is 1.20 Å. Mo(1) is bonded in a single-bond geometry to one K(2) atom.
