Abstract
The crystal structure of the triclinic compound Ag4(NH3)5Mo(CN)8- 1,5H2O could be refined in space group P1̄ (at T = 179 K: a = 974.6, b = 1477.6, C = 775.5 pm, α = 102.5, β = 94.6, y = 81.5°, Z = 2. Rg = 0.044 for 2744 independent reflections). The [Mo(CN)8]4_-groups form distorted square antiprisms with mean distances Mo-C = 215.7, C-N = 115.1 pm. They are connected to a puckered layer via four of their nitrogen ends which are tetrahedrally coordinated to silver (Ag-N = 226.7 pm). In between these layers and more or less tightly coordinated to their free cyano-N atoms dumbbells [CNAgNH3] and [Ag(NH3)2]+ are embedded. Their variation of distances and angles (Ag-N: 213 ... 216 pm, N-Ag-N: 150 ... 174°) is discussed.
