1-Butyl-3-methyl­imidazolium tri­bromido­(tri­phenyl­phosphane-κP)nickelate(II) butan-1-ol hemisolvate

The solvated title salt, (C(8)H(15)N(2))[NiBr(3)(P(C(6)H(5))(3))]·0.5C(4)H(10)O, was obtained in the form of single crystals directly from the reaction mixture. The mol­ecular structure consists of separated 1-butyl-3-methyl­imidazolium cations, tri­bromido­(tri­phenyl­phosphane)nickelate(II) anions and half a solvent mol­ecule of 1-butanol, all connected via multiple hydrogen contacts to form a three-dimensional network. The co-crystallized 1-butanol mol­ecule is disordered and adopts two orientations. The central C—C bonds of both orientations are located on an inversion centre (Wyckoff site 2b of space group P2(1)/n). Thereby, each orientation has again two orientations with the OH group being located either on one or the other side of the C(4) alkyl chain. The dried solvent-free compound exhibits a relatively low melting point (m.p. = 412 K). [Image: see text]
