Bis[3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]nickel(II) tetrahydrate
In the title complex, [Ni(C11H9ClN3O2)2]·4H2O, the Ni atom is coordinated by four N atoms and two O atoms derived from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The cis-N4O2 donor set defines a distorted octahedral geometry. In the crystal structure, the complex and water molecules are linked by O—H⋯O hydrogen bonds.
Bis[3‐chloro‐6‐(3,5‐dimethyl‐1H‐pyrazol‐1‐yl‐κN2)picolinato‐κ2N,O]cobalt(II) 2.5‐hydrate
In the title compound, [Co(C11H9ClN3O2)2]·2.5H2O, the CoII atom, which lies on a twofold rotation axis, is coordinated by four N atoms and two O atoms from two ligands in a distorted octa­hedral geometry. In the crystal structure, mol­ecules are linked together by inter­molecular O—H⋯O hydrogen bonds.
2,5-Diphenyloxazole, 3,5-diphenylisoxazole and 3-amino, 5-methylisoxazole complexes with iron(III) salts
Abstract A number of iron(III) complexes with 2,5-diphenyloxazole (PPO), 3,5-diphenylisoxazole (3,5-diPhisox) and 3-amino, 5-methylisoxazole (3-AMI) have been isolated. The compounds are of the type Fe(L) n X 3 · m H 2 O where L = PPO, n 1, 2, 3, 6, X = Cl, Br, ClO 4 , m = 0,6; L = 3,5-diPhisox and 3-AMI, n = 3, 4, 6, X = Cl, Br, ClO 4 , m = 0–6. The complexes have been studied by chemical analysis, magnetic moments, infrared, electronic, Mossbauer spectra and molar conductivity values. The ligands act a monodentate N ring bonded and the compounds are hexacoordinate in the solid state with the exception of the tetrahedral Fe(PPO)Br 3 and the five coordinate Fe(PPO) 2 Cl 3 . The magnetic moments, are generally in agreement with those expected for high spin FE(III) complexes. Only the perchlorate derivatives according also to the Mossbauer spectra present magnetic moments values, due to a low spin Fe(III) states
