{μ-6,6'-Dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}dimethanoltrinitratonickel(II)praseodymium(III) methanol disolvate.

In the title dinuclear complex, [NiPr(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)OH)(2)]·2CH(3)OH, the Ni(II) ion is coordinated by two O atoms and two N atoms of a Schiff base ligand and by two methanol ligands, forming a slightly distorted octa-hedral geometry. The Pr(III) ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from a Schiff base ligand, forming a distorted bicapped square-anti-prismatic environment. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect complex mol-ecules and methanol solvent mol-ecules to form (10) sheets.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
