A series of (κ2-N,O)-salicylaldiminato Ni(II)-methyl pyridine complexes 7-pyr and 8-pyr derived from 3,5-diiodosalicyaldehyde (3a) and 3-(9-anthryl)salicylaldehyde (3b), and terphenylamines 2,6-(3,5R-4-R′-C6H2)2C6H3-NH2 (4a, R ) CF3, R′ ) H; 4b, R ) tBu, R′ ) H; 4c, R ) tBu, R′ ) OH; 4d, R ) Me, R′ ) H; 4e, R ) Me, R′ ) MeO; 4f, R ) MeO, R′ ) H; 4g, R ) MeO, R′ ) MeO), was prepared by reaction ...

To develop a new spin-crossover functional material, a magnetic hybrid compound [Fe(qsal)2][Ni(mnt)2] was designed and synthesized (Hqsal = N-(8-quinolyl)salicylaldimine, mnt = maleonitriledithiolate). The temperature dependence of magnetic susceptibility suggested the coexistence of the high-spin (HS) Fe(III) cation and π-radical anion at room temperature and a magnetic transition below 100 K....

The phase transitional behavior of two homologous series of five-ring banana-shaped compounds comprising fluorine substituents synthesized through covalent linking of two chemically dissimilar rod-like anisometric cores (arms) to central 1,3-phenylene is reported. The novelty of these molecules originates from the fact that the molecules are highly nonsymmetrical. One of the arms, which is eith...

Phosphino-phenolate neutral nickel catalysts 1-3/B(C6F5)3, without the help of any organoaluminum compound, were found to be efficient catalytic systems for norbornene polymerization and its copolymerization with norbornene derivatives. The amount of B(C6F5)3 required for achieving a high efficiency (3 equiv.) was markedly lower compared to previous reports, and high molecular weight polymers w...

A series of water-soluble Rh(i) mononuclear complexes of general formula: [Rh(sulphsal-X-R)(COD)] [sulphsal = sulphonated salicylaldimine, COD = cyclooctadiene; where R = H, Cl, CH3 and X = H, (t)Bu] have been synthesized. All the compounds were characterised using various spectroscopic and analytical techniques such as nuclear magnetic resonance spectroscopy, infrared spectroscopy, single crys...

The asymmetric unit of the title compound, [Mn(C(18)H(18)N(2)O(4))(CH(3)OH)(H(2)O)]ClO(4)·0.5H(2)O, contains two complex cations and two perchlorate anions, one of which is disordered over two positions in a 0.767 (8):0.233 (8) ratio. The Mn(III) atoms are in distorted octa-hedral environments. In addition to the equatorial tetra-dentate salicylaldimine ligand, each Mn is axially coordinated by...
