“…Crystal structures of (NEt4)[Ni(dmit)21 and (NBun)[Ni(dmit)21 have already been determined. The former is a one-dimensional zigzag chain with interchain distances > 3.8 A (Groeneveld, Schuller, Kramer, Haasnoot & Reedijk, 1986;Kramer, Groeneveld, Joppe, Brom, de Jongh & Reedijk, 1987). The latter is, according to the atomic positions given by Lindqvist, Andersen, Sieler, Steimecke & Hoyer (1982), a network of intermolecular sulfur interactions along the x and y axes with no contacts in the z direction.…”
