The single electron transfer (SET) reactivity of metal alkyls and hydrides is currently receiving growing attention [1-3]. Thus, it has been demonstrated that aluminum species AIX3 (X = R [4], H [5], Cl [6]) can react with reducible carbonyl compounds to form aluminium containing radical complexes [4-6]. Besides carbonyl compounds, certain N-heterocycles can also be used as electron transfer su...

In the title compound, [Cu(C(15)H(11)N(3)O(3))(C(10)H(8)N(2))], the Cu(II) atom is five-coordinated in a distorted square-pyramidal CuN(3)O(2) geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from the 2,2'-bipyridine ligand. The axial position is occupied by the other N atom of the 2,2'-bipyridine ligand. The crystal struct...

several novel mononuclear zn(ii) complexes, [zn(bpy)l2], where bpy=2,2’-bipyridine and l=monoanions of phenylcyanamide (pcyd), 4-methylphenylcyanamide (4-mepcyd), 3,5-dimethylphenylcyanamide(3,5-me2pcyd),4-methoxyphenylcyanamide(4-meopcyd), 3,5-dimeth-oxyphenylcyanamide (3,5-meo2pcyd), 3-chlorophenylcyanamide (3-clpcyd), 2,3-dichlorophenyl-cyanamide (2,3-cl2pcyd), 4-bromophenylcyanamide (4-brpc...

The title compound, (C(10)H(9)N(2))[Al(C(7)H(3)NO(4))(2)]·3H(2)O or (2,2'-bipyH)[Al(pydc)(2)]·3H(2)O (where 2,2'-bipy is 2,2'-bipyridine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of aluminium(III) nitrate nona-hydrate with pyridine-2,6-dicarboxylic acid and 2,2'-bipyridine in a 1:2:4 molar ratio in aqueous solution. This compound is composed of an anionic ...

The crystal structure of the title salt, [Mn(C(10)H(8)N(2))(H(2)O)(4)][Mn(2)(C(8)H(3)O(7)S)(2)(C(10)H(8)N(2))(2)(H(2)O)(4)]·4H(2)O, consists of mononuclear manganese(II) cations, dinuclear manganate(II) dianions and uncoordinated water mol-ecules. The dianion is located about an inversion center; the Mn(II) atom is coordinated by a 2,2'-bipyridine ligand, a sulfonatoisophthalate group, a water ...

A nanoscopic pseudorotaxane (1)2 subset2 composed of the gold rectangle [Au4(mu-PAnP)2(mu-bipy)2](OTf)4 and the linear template 4,4'-bis(9''-anthryl)biphenyl was assembled (PAnP = 9,10-bis(diphenylphosphino)anthracene); bipy = 4,4'-bipyridine).

The combination of 2-hydroxy-propane-1,2,3-tricarboxylic acid (H(3)hypta, also called citric acid) and 4,4'-bipyridine (4,4'-bipy) in a 1:1.5 molar ratio leads to the formation of the title mol-ecular cocrystal, 1.5C(10)H(8)N(2)·C(6)H(8)O(7). The asymmetric unit contains one and a half 4,4'-bipy units, with one lying across a centre of inversion, and one H(3)hypta mol-ecule. The significant dif...
