In the title dinuclear complex, [NiPr(C₁₉H₂₀N₂O₄)(NO₃)₃(CH₃OH)₂]·2CH₃OH, 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 octahedral 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-antiprismatic environment. In the crystal structure, intermolecular O—H⋯O hydrogen bonds connect complex molecules and methanol solvent molecules to form (10 $[\overline{2}]$ ) sheets.

Comment top

The molecular structure is shown in Fig. 1. The hexadentate Schiff base ligand links Ni^II and Pr^III ions to form a dinuclear complex via two bridging phenolate O atoms, similar to reported copper-lanthanum complexes of the same ligand (Elmali & Elerman (2003,2004). The Pr^III ion is ten-coordinated by four O atoms from the Schiff base ligand and six O atoms from three chelating nitrate ligands. The Ni^II ion is coordinated by two N atoms and two O atoms from the Schiff base ligand and two methanol oxygen atoms. In the crystal structure, intermolecular O—H···O hydrogen bonds connect complex molecules and methanol solvent molecules to form (1 0 - 2) sheets.

Experimental top

The title complex was obtained by the treatment of Ni(II)acetate tetrahydrate (0.0622 g,0.25 mmol) with the Schiff base (0.0855 g,0.25 mmol) in methanol (25 ml) at room temperature. Then the mixture was refluxed for 3 h after the addition of praseodymium (III) nitrate hexahydrate (0.1042 g, 0.25 mmol). The reaction mixture was cooled and filtered; diethyl ether was allowed to diffuse slowly into the solution of the filtrate. Single crystals were obtained after several days. Analysis calculated for C₂₃H₃₄NiN₅O₁₇Pr: C, 32.38; H, 4.12; N, 8.18; found: C, 32.42; H, 4.02; N, 8.22

Special details top

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.
