چکیده
The two title compounds, di-mu-bromo-bis{[2,6-bis(pyrazol-1-yl-kappaN(2))pyridine-kappaN](perchlorato-kappaO)copper(II)}, [Cu(2)Br(2)(ClO(4))(2)(C(11)H(9)N(5))(2)], (I), and [2,6-bis(pyrazol-1-yl)pyridine]dibromocopper(II), [CuBr(2)(C(11)H(9)N(5))], (II), were synthesized by only slight modifications of the same reaction; compound (II) was formed by adding one molar equivalent of pyrazole (C(3)N(2)H(4)) to the reaction mixture of (I). Compound (I) is a bromo-bridged dinuclear copper(II) compound stabilized by weak interactions with the perchlorate anions (ClO(4)(-)), while (II) is a related mononuclear species, which has a distorted square-pyramidal geometry.

An iron(ii) spin-crossover metallacycle from a back-to-back bis-[dipyrazolylpyridine].
The syntheses of 4-mercapto-2,6-di(pyrazol-1-yl)pyridine (bppSH) and bis[2,6-di(pyrazol-1-yl)pyrid-4-yl]disulfide (bppSSbpp) are reported. In contrast to previously published "back-to-back" bis-[2,6-di(pyrazol-1-yl)pyridine] derivatives, which form coordination polymers with transition ions that are usually insoluble, bppSSbpp yields soluble oligomeric complexes with iron(ii) and zinc(ii).

Reaction of 2,6-difluoropyridine with 2 equiv of indazole and NaH at room temperature affords a mixture of 2,6-bis(indazol-1-yl)pyridine (1-bip), 2-(indazol-1-yl)-6-(indazol-2-yl)pyridine (1,2-bip), and 2,6-bis(indazol-2-yl)pyridine (2-bip), which can be separated by solvent extraction. A two-step procedure using the same conditions also affords both 2-(indazol-1-yl)-6-(pyrazol-1-yl)pyridine (1...

In the title complex, [Mn(CH(3)CO(2))(2)(C(11)H(9)N(5))], the Mn(II) atom is coordinated by the pyridine N atom and two pyrazole N atoms from a 2,6-bis-(pyrazol-3-yl)pyridine ligand and four O atoms from two bidentate acetate ligands. The complex mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds into a chain along [010]. π-π inter-actions between the pyridine rings and between the p...
