Crystal structure of diaqua-(2,4-dihydroxybenzoato-κ2O,O')-(2,9- dimethyl-1,10-phenanthroline-κ2N,N') nickel(II) 2,4-dihydroxybenzoate, C28H26N2NiO10

Abstract

C 28 H 26 N 2 NiO 10 ,monoclinic, P2 1 /n (no. 14), a =9.4921(9) Å, Source of materialTo asolution of 2,9-dimethyl-1,10-phenanthroline hemihydrate (0.5 mmol), 2,4-hydroxybenzoate (0.5 mmol) and sodium hydroxide (0.5 mmol) in water/ethanol(v:v=2:1, 15 ml) was added a solution of Ni(NO 3 ) 2 ×6H 2 O(0.5 mmol) in distilled water (5 ml). The resulting solution was refluxed for 10 hat333 Kand filtrated. Blue single crystals of the title compound were obtained by slow evaporation of the filtrate over four weeks.
