چکیده
In the title compound, C(14)H(30)N(2) (2+)·2Br(-)·2CH(3)OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methyl-pyrollidines, forming a linear diquaternary ammonium cation. The cation lies across a centre of inversion located between the two central C atoms of the butane chain. The asymmetric unit therefore comprises one half-cation, a bromide anion and a methanol solvent mol-ecule. In the crystal structure, the bromide anions are linked to the methanol solvent mol-ecules by O-H⋯Br hydrogen bonds.

The title compound, C(12)H(20)N(4) (2+)·2BF(4) (-), was prepared by the anion exchange of a dibromide ionic liquid with sodium tetra-fluoro-borate. The asymmetric unit contains one half of the imidazolium cation, which lies about an inversion centre at the mid-point of the central C-C bond of the linking butyl chain. The two planar imidazole rings (r.m.s. deviation = 0.0013 Å) are strictly para...

In the title compound, [Ni(C(12)H(6)O(4))(C(10)H(14)N(4))(H(2)O)](n), the coordination polyhedron around each Ni(II) atom is a distorted cis-NiN(2)O(4) octa-hedron. The naphthalene-1,4-dicarboxyl-ate and 1,1'-(butane-1,4-di-yl)diimidazole ligands bridge the Ni centres to form a two-dimensional (4,4)-network, and O-H⋯O hydrogen bonds complete the structure.
