Reaction between 4-aminopyridine and a dinuclear zinc(II) component of a Robson macrocyclic ligand has resulted in the formation of a molecular ladder element motif. X-ray single crystal structural analysis indicates that two pyridine rings are assembled at the same direction of the macrocycle, which are placed in a nearly parallel way via

摘要

Several chiral copper(II) complexes of optically active Schiff bases (R,R)-4a-c, which have central seven-membered chelate rings, have been synthesized and characterized. X-ray single crystal analysis of a typical compound indicated that the complex is monomeric and the geometry around the metal atom is very distorted tetrahedral. All the complexes have been tested as catalysts for asymmetric oxidation of methyl phenyl sulfide. The mechanism of the catalytic reaction in the presence of these complexes has been tentatively elucidated.

摘要

A chiral heptanuclear nickel(II) complex [NiII(NiII 2L)3(μ3-OH)2]·3H2O [H4L=(2R,3R)-1,4-bis(3,5-di-tert-butylsalicylideneamino)-2,3-butanediol], containing two μ3-OH bridges, has been prepared and structurally characterized; its thermal and magnetic properties were investigated.

【期刊论文】A novel coordination polymer constructed from 1D neutral chains via inter-chain π-π stacking and hydrogen bonding

摘要

A novel 1D neutral coordination polymer, {[Cu(dtmp)(dmf)Cl2]dmf}n (1) (dtmp=1,6-di(triazole-1-yl-methyl)-4-methylphenol, dmf=dimethyl formamide) was synthesized by reacting CuCl2 Æ 2H2O with the dtmp ligand. The crystal and molecular structure of the complex was determined by X-ray diffraction, in which the coordination geometry around the copper center is slightly distorted trigonal bypyramidal. One-dimensional chains have been formed through the metal and the ligand via oordination bonds, which are assembled further into a two-dimensional network by inter-chain synergic π-π stacking and hydrogen bonding.
