چکیده
The Co(II) ion in the title complex, [Co(2)(C(4)H(5)O(2))(4)(C(15)H(13)N(5))(2)]·2H(2)O, has a distorted square-planar coordination formed by the bridging bidentate N,N'-di-4-pyridylpyrid-ine-2,6-diamine (dapmp) ligands and two monodentate carboxyl-ate groups from methacrylates. Two dapmp ligands bridge two Co atoms, forming a dinuclear complex arranged around an inversion centre. N-H⋯O and O-H⋯O hydrogen bonds involving the solvent water mol-ecule result in the formation of a three-dimensional network. The aliphatic moiety of one of the methacrylate groups is disordered over two positions with fixed occupancies of 0.67 and 0.33.

The asymmetric unit of the binuclear title complex, [Hg(2)Cl(4)(C(17)H(13)N(5)O(2))(2)]·2C(3)H(7)NO, contains one-half of the centrosymmetric mol-ecule and one dimethyl-formamide solvent mol-ecule. The Hg(II) atom is four-coordinated by two N atoms from two ligands and two Cl atoms in a distorted tetra-hedral coordination geometry. Intra-molecular N-H⋯O hydrogen bonds may be effective in the st...

In the title complex, {[HgI(2)(C(17)H(13)N(5)O(2))]·C(3)H(7)NO}(n), the Hg atom is coordinated by two I atoms and two N atoms from two different ligands in a distorted tetra-hedral environment. Hg atoms are bridged by N,N'-di-3-pyridylpyridine-2,6-dicarboxamide ligands, forming a helical chain running along the a axis.
متن کاملAn 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).
