Abstract top

The title compound, [Cu(C6H8N2)(C13H15N3)](ClO4)2, is a mixed ligand complex with the CuII atom coordinated by (6-methyl-2-pyridylmethyl)(2-pyridylmethyl)amine, acting as a tridentate ligand, and 2-(2-aminomethyl)pyridine, as a bidentate ligand, leading to an N5 square-pyramidal geometry. The amine H atoms are involved in hydrogen bonding to the perchlorate O atoms and there are extensive but weak intermolecular C-H...O interactions in the crystal structure. The perchlorate ions are each disordered over two positions, with site occupancies of 0.601 (8):0.399 (8) and 0.659 (11):0.341 (11).

Comment top

The geometry around the CuII ion in (I), Fig. 1, is best described as a distorted square-pyramid (τ = 0.224; Addison et al., 1984), with an amine-N2 atom and three pyridine-N atoms (N1A, N1B, and N1) defining the basal plane. The Cu—Npyridyl bond distances are in the range of 1.993 (3)–2.039 (3) Å, and a Cu—Namine bond distance of 1.998 (3) Å. The axial position is occupied by the amine-N atom of the tridentate (6-methyl-2-pyridylmethyl)(2-pyridylmethyl)amine ligand with a bond distance of 2.195 (3) Å consistent with a Jahn–Teller elongation. In (I), the Cu—Npyridyl and Cu—Namine bond distances of 1.993 (3) and 1.998 (3) Å, respectively, are shorter for the 2-(2-aminomethyl)pyridine ligand. The amine H atoms are involved in hydrogen bonding to the perchlorate-O atoms and there are extensive but weak intermolecular C—H···O interactions in the crystal structure (Fig. 2 & Table 1).

Experimental top

Complex (I) was synthesized by reacting one equivalent each of the ligands (6-methyl-2-pyridylmethyl)(2-pyridylmethyl)amine and 2-(2-aminomethyl)pyridine with Cu(ClO4)2.6H2O and triethylamine in methanol solution. After stirring the mixture for 12 h, the resulting precipitate was isolated and re-dissolved in acetonitrile solution. Dark-blue crystals suitable for X-ray diffraction analysis were obtained by layering this solution with diethyl ether.

Refinement top

The two perchlorate anions are disordered over two conformations with occupancy factors of 0.601 (8), 0.399 (8) for the Cl1-perchlorate anion, and 0.659 (11), 0.341 (11) for the Cl2-perchlorate. Each of the perchlorates was constrained to adopt a tetrahedral geometry. The H atoms were included in the riding model approximation with N—H = 0.90–0.91 Å and C—H = 0.93–0.97 Å, and with Uiso(H) = 1.2Ueq(C, N) (1.5Ueq(C) for methyl-H).

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.
