چکیده
The title compound, [Ni(C15H11N3)2][Au(CN)2]2, is an ionic compound composed of bis-(2,2':6',2''-terpyridine)-nickel(II) dications and dicyanidoaurate(I) anions in a 1:2 ratio. The two tridentate terpyridine ligands define the coordination of the Ni(2+) cation, resulting in a nearly octa-hedral coordination sphere, although there is not any imposed crystallographic symmetry about the Ni(2+) site. The two nearly linear dicyanidoaurate(I) anions [C-Au-C = 179.0 (2) and 178.2 (2)°] contain a short aurophilic inter-action of 3.1017 (3) Å. The structure does not demonstrate any π-π stacking. Non-classical C-H⋯N inter-actions between the cations and anions build up a three-dimensional network.

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...

The crystal structure of the title compound, [Ni(C(6)H(6)N(4)S(2))(H(2)O)(4)][Ni(C(7)H(3)NO(4))(2)]·3H(2)O, consists of Ni(II) complex cations, Ni(II) complex anions and lattice water mol-ecules. The Ni(II) ions in both the complex cation and anion assume a distorted octa-hedral coordination geometry. O-H⋯O, N-H⋯O and C-H⋯S hydrogen bonds occur in the crystal structure.
