The structures of (MePh3P)[M(dca)3] (M = Fe, Co, Ni and dca = dicyanamide, N(CN)2-) are isomorphous and contain anionic [M(dca)3]- networks in which octahedral metal ions are bridged by bidentate μ1,5 dca anions, to generate three-dimensional (3D) five-connected networks. The structures of (EtPh3P)[M(dca)3] (M = Mn, Co, Ni) are also isomorphous and contain similar anionic networks to the MePh3P+ structures. In both sets of structures, the cations appear to perform a templating function and lie in pairs within cavities in the anionic network. These cation pairs show pseudo-6-fold phenyl embraces. No long-range magnetic ordering intrinsic to these materials was observed, although traces of the ferromagnets α-[Co(dca)2] and α-[Ni(dca)2] were observable in very small applied fields, at 9 and 21K, respectively.
