Özet

Trans-bis(2-pyridinepropanol)bis(saccharinato)nickel(II), [Ni(sac)(2)(pypr)(2)], where sac and pypr are the saccharinate anion and the 2-pyridinepropanol molecule, respectively, crystallizes in the triclinic space group P1 (No. 2) with a = 8.1981(8), b = 9.9680(10), c = 10.4956(10) Angstrom, alpha = 90.740(3)degrees beta = 108.142(3)degrees, gamma = 111.025(3)degrees, Z = 1, V = 1.537 Angstrom(3), The structure of the nickel(II) complex consists of neutral molecules in which the nickel(II) ion sits on a center of symmetry and is octahedrally coordinated by two sac ligands, and two neutral pypr ligands. The pypr acts as a bidentate N- and O-donor ligand forming a seven-membered chelate ring, while sac behaves as a monodentate O-donor ligand via the carbonyl O atom. The Ni-N bond distance is 2.1016(15) Angstrom, whereas the Ni-O-pypr and Ni-O-sac bond distances are 2.1280(12) and 2.0792(11) Angstrom, respectively. The individual molecules are held together with a strong hydrogen bond between the hydroxyl O atom of pypr and N atom of sac and the C-(HO)-O-... type weak hydrogen bonds between some ring hydrogen atoms of pypr and sac, and the carbonyl and sulfonyl O atoms of sac in the neighbouring molecules.
