title: [N,N'-(1,2-Diphenyl-ethane-1,2-di-yl)bis-(pyridine-2-carboxamidato)]nickel(II) diethyl ether hemisolvate.
abstract: In the title compound, [Ni(C(26)H(20)N(4)O(2))]·0.5C(4)H(10)O, the central metal ion is coordinated by four atoms of the tetra-dentate picolinamide ligand, forming a slightly distorted square-planar configuration, with an average Ni-N(pyridine) distance of 1.94 Å and an average Ni-N(amide) distance of 1.83 Å. The asymmetric unit contains one half-molecule of diethyl ether; this solvent molecule is disordered across a twofold rotation axis..
