K Ag Ag Ge
KAgAgGe1 is gamma nitrogen-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgGe1 clusters and two KAg clusters. In each AgGe1 cluster, Ag(1) is bonded in a single-bond geometry to one Ge(1) atom. The Ag(1)-Ge(1) bond length is 0.49 Å. Ge(1) is bonded in a single-bond geometry to one Ag(1) atom. In each KAg cluster, K(1) is bonded in a single-bond geometry to one Ag(2) atom. The K(1)-Ag(2) bond length is 0.83 Å. Ag(2) is bonded in a single-bond geometry to one K(1) atom.
