چکیده
The mol-ecule of the title compound, C(18)H(28)N(2)Si(2), occupies a special position on an inversion centre. The Si-CH(2)-C(ipso) plane is approximately orthogonal to the plane of the pyridine rings, the corresponding dihedral angle being 82.0 (2)°.

5,5′-Bis[(1H-imidazol-1-yl)methyl]-2,2′-bipyridine methanol disolvate
The title compound, C(18)H(16)N(6)·2CH(3)OH, was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one methanol solvent mol-ecule. The dihedral angle between the pyridine and imida...
متن کامل5,5′-Bis[(2,2,2-trifluoroethoxy)methyl]-2,2′-bipyridine
The complete molecule of the title compound, C(16)H(14)F(6)N(2)O(2), is generated by crystallographic inversion symmetry, which results in two short intramolecular C-H⋯N hydrogen-bond contacts per molecule. In the crystal, aromatic π-π stacking [centroid-centroid distance = 3.457 (2) Å] and weak C-H⋯π inter-actions occur. A short H⋯H [2.32 (3) Å] contact is present.

Synthesis of bisfunctionalized unsymmetrical 2,2'-bipyridines 8 or their sulfonyl derivatives 12a,b are described. They were prepared via the Diels-Alder reaction of 1-methyl-4-pyrrolidin-1-yl-1,2,3,6-tetrahydropyridine (6) with 3,3'-bis(methyl- sulfanyl)-5,5'-bi-1,2,4-triazine (1). The reaction leads to the single cycloaddition product 7 which undergoes Diels-Alder reaction with cyclic enamine...

The title complex, [Cd(C(2)HN(9))(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·H(2)O, was prepared under hydro-thermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent mol-ecule and a solvent water mol-ecule. The Cd(II) ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA(-) anion ligand [where H(2)BTA is N,...

In the title compound, [Co(C(8)H(5)Cl(2)O(3))(C(12)H(12)N(2))], the Co(II) atom, lying on a twofold rotation axis, is coordinated by four O atoms from two chelating 2,4-dichloro-phen-oxy-acetate ligands and two N atoms from a 5,5'-dimethyl-2,2'-bipyridine ligand, displaying a distorted octa-hedral geometry. A three-dimensional supra-molecular structure is formed through inter-molecular C-H⋯O hy...
