    Abstract:
    The preparation of the crystalline complex [Na{NH3·BH2(CN)}6]I from NMe3·BH2I and NaCN in liquid NH3 is described. Structural details have been obtained by single-crystal X-ray analysis of therhombohedral crystals which belong to space group R3, with a = b = c = 8.506(4) Å, α = β = γ = 82.54(4)°, and Z = 1. The structure has been solved by the heavy-atom method from 1 293 unique reflections measured by diffractometer and refined by full-matrix least-squares calculations to R 0.063. The NH3·BH2(CN) units are arranged in a regular octahedral manner about both the Na+ and I- ions with Na+ ⋯ N(cyano) 2.487(4) Å and Na+ ⋯ N-C 134.2(4)°; evidence for a linear correlation between such distances and angles in related complexes is presented. The B-N, B-C, and C≡N distances are 1.581(8), 1.579(8), and 1.152(7) Å, respectively.
