Nuclearity of nickel and mixed sodium-nickel complexes: dependence on the spacer in chelating pyridine-alcoholate ligands.
Modifying the HL/Ni(ii) stoichiometry in the reaction between pyridine-2-ylmethanol (HL), [NiCl(2)(DME)] and NaH affords [Na(3)Ni(4)L(9)(mu(3)-OH)]Cl (1) or the new, unusual Na(10)Ni(6) polynuclear complex [Na(8)(NaL)(2)(NiL(3))(6)(mu(5)-OH)(2)] (2); starting from pyridine-2-ylethanol (HL(Et)) instead yielded [Ni(3)(mu-L(Et))(2)(mu(3)-L(Et))(2)(L(Et))(HL(Et))]Cl, whose magnetic properties are reported.
