The title compound, [Zn(2)(C(12)H(27)O(3)SSi)(4)(C(10)H(8)N(2))(CH(4)O)], is a binuclear complex with the two Zn(II) atoms linked via a bridging 4,4'-bipyridyl ligand. One of the Zn(II) atoms is penta-coordinated by two O,S-chelating tri-tert-butoxy-silanethiol-ate units and one N atom of a 4,4'-bipyridine ligand, and the other Zn(II) atom is tetra-hedrally coordinated by two tri-tert-butoxy-si...

The asymmetric unit of the title compound, 7C(10)H(8)N(2)·4C(10)H(13)N(3)O(2)S·2H(2)O, contains two independent 2,4-hydroxy-benzaldehyde 4-ethyl-thio-semicarbazone mol-ecules, three and a half 4,4'-bipyridine mol-ecules and one water mol-ecule. Two of the 4,4'-bipyridine mol-ecules lie on general positions and the other three on centers of inversion. The two 4,4'-bipyridine mol-ecules on genera...

The title compound, C(10)H(8)N(2)·2C(7)H(5)NO(4),was obtained unintentionally as the harvested product of the hydro-thermal reaction between Co(OAc)(2)·4H(2)O and 4,4'-bipyridine in the presence of 3-nitro-phthalic acid. In the reaction, 3-nitro-phthalic acid is transformed into 3-nitro-benzoic acid by an in situ deca-rboxylation reaction, in which the carboxyl-ate group is not deprotonated and...

In the title compound, {[Pb(sbc)(bpy)]·2H(2)O}(n) [bpy is 2,2'-bipyridine (C(10)H(8)N(2)) and sbc is the 2-sulfonatobenzoate dianion (C(7)H(4)O(5)S)], the Pb(II) ion is bonded to four O atoms including carboxyl-ate and sulfonate from three sbc dianions, and two N atoms from a chelating 2,2'-bipyridine ligand. The sbc ligand acts as a μ(3)-bridging ligand by one O atom of the sulfonate group and...

The asymmetric unit of the title compound, [Hg(2)Br(4)(C(12)H(12)N(2))(2)], contains one half-mol-ecule. The Hg(II) atom is five-coordinated in a trigonal-bipyramidal configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, two bridging Br and one terminal Br atom, leading to a centrosymmetric dimeric mol-ecule. There is a π-π contact between the pyridine rings [cen...

A new precursor 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile has been synthesized by the reaction of 2-cyanomethylbenzonitrile, carbon disulfide and methyl iodide under basic conditions. The reaction of 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile with various functionalized aryl/heteroaryl methyl ketones or acetone under basic conditions afforded 4-amino-3-aroyl/heteroaroyl/acetyl-2-me...
