Syntheses and structures of Cd(II) and Co(II) compounds of 4-[(3-pyridyl)methylamino]benzoate anion

Three coordination polymers containing Cd(II) and Co(II), connected via 4-[(3-pyridyl)methylamino]benzoate (L^?), have been synthesized in hydrothermal conditions. In [Cd(L)Cl] _n (1), adjacent Cd(II) cations are linked by carboxylates to give a dinuclear cluster. Pairs of L^? bridge the dinuclear cluster to form double helical chains, and these chains are further linked by Cl^? to produce a 4-connected net with (4²?·?6³?·?8) topology. [CdL₂] _n (2) contains 1-D ladder-like chains. The packing structure displays a 3-D supramolecular structure, with π?···?π interactions stabilizing the framework. [CoL₂] _n (3) has a 2-D extended supramolecular structure via π?···?π interactions of 1-D coordination polymers of 3. The crystal structures of 1–3 have been determined by single-crystal X-ray diffraction. Luminescent properties for 1 and 2 are discussed.     

Synthesis and Structure Characterization of N-Phenyl-（2S）-hydroxy-3-[（2-hydroxybenzylidene）amino]propionamide

1 INTRODUCTION Schiff bases can be conveniently prepared from the corresponding aldehyde and primary amine, which, as multidentate ligands, have already received great attention. Many metal complexes of this kind of ligands have been used successfully in various re- actions, such as Diels-Alder and hetero-Diels-Alder reactions[1], kinetic resolution of racemic epoxides[2], and Nozaki-Hiyama-Kishi (NHK) reaction[3]. Recen- tly Berkessel et al. have reported that the Cr- complex of sal…     

Molecular Structure and Magnetic Properties of the Binuclear Phthalato-Bridged Species Bis[(N-(2-(Diethylamino)Ethyl)Salicylidenaminato)-Copper(II)] Trihydrate

The crystal structure of ( w -phthalato)bis[(N-(2-(diethylamino)ethyl)-salicylidenaminato)copper(II)-trihydrate,[Cu₂(salNet₂)₂(w m phthal)] · 3H₂O, where salNet₂= N-(2-(diethylamino)ethyl)salicylidenaminate, has been determined by single-crystal X-ray analysis. It crystallizes in the monoclinic system, space group P2₁/c, with a = 19.9109(9), b = 10.0465(4), c = 18.5837(8)Å, and g = 100.625(1)°. In the molecular structure the two copper(II) ions are bridged by the phthalato ligand coordinated in an amphimonodentate mode and the local geometry around both copper(II) ions is square planar. Magnetic susceptibility data for the complex as a function of temperature show weak exchange interactions. The fitting of these data to the HDVV (? = -2J ? ₁ ?₂), S₁ = S₂ = 1/2 spin exchange model, yields a 2J value of -0.34 cm^-1. An orbital interpretation of the observed weak antiferromagnetic interactions is presented based on the results of extended Hückel calculations on a model molecule.     

Synthesis and Crystal Structure of 4-Nitro-2- [（2-diethylaminoethylimino）methyl]phenol

1 INTRODUCTION Schiff base ligands have played an important role in the development of coordination chemistry as they readily form stable complexes with most metal ions[1～4]. These complexes are very interesting in many fields, such as catalysis and enzymatic reac- tions[5, 6], magnetism and molecular architectures[7～9]. The complexes derived from the similar tridentate Schiff base ligand 2-[(2-dimethylaminoethylimino)- methyl]phenol[10, 11] and its derivatives[12～14] have been widely …
