In the cyrstal structure of the title compound, [Cu(NCS)(C₁₈H₂₀N₂O₂)]_n, the Cu^I atom is coordinated in a distorted tetrahedral geometry by two imino N atoms from a bidentate chelating Schiff base ligand, and one N and one S atoms from two thiocyanate anions. The thiocyanate anion bridges the Cu^I atoms, forming a zigzag chain along [101]. The Schiff base ligand adopts an E,E configuration and the dihedral angle between the terminal benzene rings is 53.68 (8)°.

Comment top

Synthesis and characterization of copper(I) complexes with bidentate chelating Schiff base ligands have received much attention in recent years (Khalaji, Brad & Zhang, 2008; Khalaji, Welter et al., 2008; Zhao et al., 2008). Depending on the ligands involved, copper(I) complexes can show a wide variety of structures (Amirnasr et al., 2006; Khalaji & Welter, 2006; Khalaji, Brad & Zhang, 2008; Khalaji, Welter et al., 2008). As part of a general study of transition metal complexes with bidentate chelating Schiff base ligands (Khalaji & Welter, 2006; Khalaji, Brad & Zhang, 2008; Khalaji, Welter et al., 2008), here, we reported the synthesis and the crystal structure of the title compound, (I).

The crystal structure of the title compound, (I), is shown in Fig. 1. The Schiff base (3-MeO-ba)₂en ligand chelates the Cu^I atom to form a five-membered ring, with N2—Cu1—N3 = 83.78 (4)°, which is in good agreement with the corresponding angles in related complexes (Khalaji & Welter, 2006; Khalaji, Brad & Zhang, 2008; Khalaji, Welter et al., 2008). The Cu—N and Cu—S distances (Table 1) are similar to those in the other copper(I) complexes. The C12—N3 and C9—N2 bond lengths of 1.2717 (18) and 1.2665 (18) Å, respectively, conform to the value for a C=N double bond, while the N2—C10 and N3—C11 bond lengths of 1.462 (2) and 1.476 (2) Å, respectively, conform to the value for a C—N single bond. These C—N lengths are comparable to the corresponding values observed in other tetrahedral copper(I) complexes with bidentate chelating Schiff base ligands (Khalaji & Welter, 2006; Khalaji, Brad & Zhang, 2008; Khalaji, Welter et al., 2008). The bidentate chelating (3-MeO-ba)₂en ligand adopts an E,E configuration in this structure.

Experimental top

The title compound, (I), was synthesized using a method analogous to the literature procedure (Khalaji & Welter, 2006), except that CuI was replaced with CuNCS. Single crystals suitable for data collection were obtained by slow evaporation from an acetonitrile solution at 273 K.

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.
