4,4′-Dimethyl-2,2′-bipyridinium dichloride
In the title compound, C(12)H(14)N(2) (2+)·2Cl(-), the 4,4'-dimethyl-2,2'-bipyridinium cation is essentially planar (r.m.s. deviation for all non-H atoms = 0.004 Å) and is located on a crystallographic inversion centre. The cations and chloride anions lie in planes parallel to (111) and are connected by N-H⋯Cl and C-H⋯Cl hydrogen bonds.

In the title compound, C(12)H(14)N(2) (2+)·2BF(4) (-), the cation has a centre of symmetry at the mid-point of the central C-C bond. π-π inter-actions, with a shortest atom-to-atom distance of 3.757 (4) Å, extend the crystal structure into a one-dimensional supra-molecular chain.
متن کامل1,1′-Dimethyl-4,4′-bipyridinium bis(triiodide)
In the title compound, C(12)H(14)N(2) (2+)·2I(3) (-), the 1,1'-dimethyl-4,4'-bipyridinium (DMBP) dication is charge balanced by two triiodide ions. The DMBP dication is planar within 0.010 (5) Å. The asymmetric unit contains only half of the dication, the other half being generated by an inversion center. Weak C-H⋯I inter-actions link the ions into sheets parallel to (121).
متن کامل4,4′-Bipyridinium 1,4-phenylenediacetate
The title compound, C(10)H(10)N(2) (2+)·C(10)H(8)O(4) (2-), has inversion centres located at the geometric centres of the 1,4-phenyl-enediacetate anion and 4,4'-bipyridinium cation. The anions and cations are connected by N-H⋯O hydrogen bonds, forming one-dimensional supra-molecular chains, which inter-act with each other via π-π inter-actions [centroid-centroid distance = 3.938 (2) Å], buildin...
متن کاملSynthesis and Characterization of 4, 11-dimethyl-1, 4, 8, 11, tetraazabicyclo hexadecane Chromium
A new complex of Chromium(III) and the cross-bridged macrocyclic ligand 4,11-dimethyl-1,4,8,11tetraazabicyclo[6.6.2] hexadecane has been synthesized. Complexation of Tungsten, Vanadium, and Molybdenum was unsuccessful. The Cr(III)(L) complex was characterized using UV-Visible spectroscopy λmax = 583nm , IR Spectroscopy, X-Ray Crystallography, and magnetic susceptibility ueff = 3.95. These tests...
