两个含有平行交替链的新型二氰胺配位高聚物: {Mn(dmpz)[N(CN)2]2}2和{Cu(dmpz)[N(CN)2]2}2

Two new dicyanamide coordination polymers, {Mn(dmpz)[N(CN)2]2}2 (1) and {Cu(dmpz)[N(CN)2]2}2 (2)(dmpz=3,5-dimethylpyrazole), were synthesized and characterized by single crystal X-ray diffraction analysis and IR spectroscopy. In 1 and 2 the metal ions have two different coordination modes, where one is coordinated to four dicyanamide anions and two monodentate dmpz molecules to form a slightly distorted octahedral geometry, while the other adopts octahedral geometry, surrounded by four nitrile N atoms and two amide N atoms of the dicyanamide anions. Both complexes contain two alternating chains that are parallel to each other.

Synthesis,reactivity and electrochemical properties of substituted cyclopentadienyl cobalt (Ⅲ) complexes

Cyclopentadienyl cobalt complexes (n5-C5H4R)CoLI2 [L = CO,R=-COOCH2CH=CH2 (3); L=PPh3,R=-COOCH2-CH=CH2 (6); L= P(p-C6H4CH3)3,R=-COOC(CH3) = CH2 (7),-COOCH2C6H5(8),-COOCH2CH = CH2 (9)] were prepared and characterized by elemental analyses,1H NMR,IR and UV-vis spectra.The reaction of complexes (n5-C5H4R)CoLI2[L=CO,R=-COOC(CH3)=CH2 (1) ,-COOCH2C6H5(2):L=PPh3,R =-COOC(CH3)=CH2 (4),-COOCH2C6H5(5)] with Na-Hg resulted in the formation of their corresponding substituted cobaltocene (n5-C5H4R)2Co [R= -COOC(CH3) = CH2 (10),-COOCH2C6H5 (11) ].The electrochemical properties of these complexes 1-11 were studied by cyclic voltammetry.It was found that as the ligand (L) of the cobalt (Ⅲ) complexes changing from CO to PPh3 and P(p-tolyl)3,their oxidation potentials increased gradually.The cyclic voltammetry of α,α'-substituted cobaltocene showed reversible oxidation of one electron pro-
