Diacetonitrile[N,N'-bis(3,4,5-trimethoxybenzylidene)ethylenediamine]copper(I) perchlorate

Abstract top

In the title compound, [Cu(C2H3N)2(C22H28N2O6)]ClO4, the Cu atom is coordinated by two N atoms from one bidentate Schiff base ligand and two N atoms from two acetonitrile groups. The Cu atom adopts a tetrahedral geometry. The Cu-N(ligand) distances are 2.076 (3) and 2.089 (3) Å, and the Cu-N(acetonitrile) distances are 1.964 (4) and 1.975 (4) Å.

Comment top

Copper(I) complexes have long been used in organic synthesis as catalyst (Dakin et al., 2000), and the design of supramolecular arrays (Amirnasr et al., 2006).

The coordination of the Cu atom is nearly tetrahedral (Fig. 1), with four N atoms, two from two acetonitrile groups and the other two from one bidentate Schiff base ligand (3,4,5-MeO-ba)2en, forming the CuN4 chromophore. Although a tetrahedral geometry is to be expected for a four-coordinated Cu(I) complexes, the geometry about the Cu(I) in this structure is distorted by the bite angle of the chelating ligand. The N(1)—Cu(1)—N(2) angle is 84.97 (13) and N(3)—Cu(1)—N(4) angle is 103.04 (16)° in this structure being smaller than the tetrahedral values, however, other angles are larger than the tetrahedral values, which posses approximate C2 local symmetry. The Cu—N bond lengths [Cu(1)—N(3), 1.964 (4); Cu(1)—N(4), 1.975 (4); Cu(1)—N(2), 2.076 (3) and Cu(1)—N(1) 2.089 (3) Å] agree well with the same distances in other tetrahedral copper(I) complexes (Chowdhury et al., 2000.; Dakin et al., 2000). The N(1)=C(7) and N(2)=C(13) bond lengths of 1.274 (5) and 1.277 (5) Å, respectively, conform to the value for a double bond, while the C(11)—N(1) and C(12)—N(2) bond lengths of 1.475 (5) and 1.468 (5) Å, respectively, conform to the value for a single bond and are comparable to the corresponding values observed in other tetrahedral copper(I) complexes (Chowdhury et al., 2000.; Dakin et al., 2000). The ligand adopts a Z,Z configuration in this structure.

Experimental top

The N,N'-Bis(3,4,5-trimethoxybenzylidene)ethylenediamine (3,4,5-MeO-ba)2en) ligand was prepared as reported elsewhere (Khalaji et al., 2007). The reaction between [Cu(CH3CN)4]ClO4 (0.326 mg, 0.1 mol) and the (3,4,5-MeO-ba)2en ligand (0.416 g, 0.1 mol) in 10 ml CH3CN at room temperature lead to the formation of the copper(I) complex.

Refinement top

All H atoms were positioned geometrically (C—H=0.93–0.97 Å), and refined as riding with Uiso(H)=1.2Ueq(carrier) or 1.5eq(methyl groups). All O—O distances of the ClO4- anion have been restrained to 2.35 (1) Å, and the Cl—O distances to 1.44 (1) Å. The displacement parameters of these O atoms have been restrained to an isotropic behaviour with an effective standard deviation of 0.01.

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.
