K Mo As As
MoK(As)2 is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two diarsene molecules and two MoK clusters. In each MoK cluster, K(1) is bonded in a single-bond geometry to one Mo(1) atom. The K(1)-Mo(1) bond length is 0.11 Å. Mo(1) is bonded in a single-bond geometry to one K(1) atom.
