title: Bis[2-(benzyl-amino)pyridine-κN](2-formyl-6-methoxy-phenolato-κO,O)(nitrato-κO,O')nickel(II).
abstract: In the title compound, [Ni(C(8)H(7)O(3))(NO(3))(C(12)H(12)N(2))(2)], the asymmetric unit contains a Ni(II) atom, two mol-ecules of 2-(benzyl-amino)pyridine, a mol-ecule of deprotonated o-vanillin (3-methoxy-salicylaldehydate) and a bidentate nitrate anion. The Ni(II) center is six-coordinated by two pyridine N atoms from 2-(benzyl-amino)pyridine, two O atoms from o-vanillin and two O atoms from the nitrate anion. The crystal packing shows two hydrogen bonds from the amine N-H group to the deprotonated phenol O atom of the o-vanillin moieties, as well as weak C-H⋯O secondary inter-actions. These inter-actions link the mol-ecules into ribbons in the c direction. The steric requirement of the bidentate nitrate and its small bite angle [61.01 (3)°] cause some orientation of the two 2-(benzyl-amino)pyridine groups. As a result, this coordination environment of the Ni(II) center is distorted octa-hedral, as the trans angles range from 158.65 (3) to 175.76 (3)° and the cis angles range from 61.01 (3) (for the bidentate nitrate O atoms) to 102.30 (4)°.
