(Received 9 November 2007; accepted 20 November 2007; online 6 December 2007)

The title complex, [Ni₂(C₄₂H₄₆Cl₂N₆O₂)(C₂H₃O₂)]ClO₄·2CH₃CN, was synthesized by condensation of 2,6-diformyl-4-chlorophenol with N,N-bis(aminopropyl)benzylamine in the presence of Ni^II ions. The ligand is a 28-membered macrocycle with two identical pendant arms. The coordination geometries of the Ni atoms are both octahedral. The two Ni atoms are bridged by two phenolate O atoms of the macrocyclic ligand and one acetate ligand, with an Ni⋯Ni distance of 3.147 (4) Å.

Comment top

Pendant-arm marocyclic complexes have attracted much interest in recent decades. Because there is a concept that, by having pendant arm attached at appropriate positions on the macrocyclic framework, an "opened cryptand" would result, leading to modified complexation property over the corresponding clathrochelates or simple macrocyclic precursors (Zeng et al., 1998). Transition metal complexes with pendant-arm ligands, usually synthesized by cyclocondensation of 2,6-diformyl-4- chlorophenol and diamine the stepwise template reaction, have been studies extensively (Luo et al., 2002, Zeng et al., 1998). However, the dinuclear nickel complex of this ligand(I) has not been published. Here, we report the synthesis and crystal structure of the complex.

The crystal structure is composed of complex cations, perchlorate anions and solvent acetonitrile molecules. Neither the perchlorate ion nor the acetonitrile molecules participate in coordination of the Ni atoms. The complex cation is extremely twisted owing to the flexility of macrocyclic ligand as well as the requirement of Ni coordination with donor atoms. The structure of (I) is shown in Fig. 1. The coordination geometry of Ni1 is similar to that of Ni₂. The coordination polyhedron around Ni₁ is a distorted octahedron, whose equatorial plane is formed by one imine N₆, one tertiary N₅, two phenolate O₁ and O₂ with the mean deviation of 0.0541 (4) Å. The axial positions are occupied by N₄ and O₃, respectively. the band length of Ni₁—O is fall in the range 2.033 (3)–2.082 (3) Å, but the two Ni₁—N(imine) bonds[2.081 (4) and 2.092 (3) Å, respectively] are shorter significantly than the Ni₁—N(tertiary) [2.201 (3) Å]. The Ni···Ni separation is 3.147 (4) Å. The two benzyl groups attached to N₂ and N₅ respectively are cis to each other.

Experimental top

2,6-diformyl-4-chlorophenol was prepared by a modification of the literature method (Gou & Fenton, 1994). N,N-bis(aminopropyl)- benzylamine prepared by literature method of (Turonek et al., 1995). The title complex was synthesized by the following procedure: 0.5 mmol N,N-bis(aminopropyl)-benzylamine in 15 ml of absolute methanol was added dropwise to a methanol solution (30 ml) containing 0.5 mmol 2,6-diformyl-4-methylphenol and 0.5 mmol Ni(OAc)₂.H₂O. After stirring the mixture for 10 h at room temperature, a green solution formed. A methanol solution (10 ml) containing Ni(ClO₄)₂.4H₂O(0.5 mmol) was added dropwise. A yellow-green solution was produced after stirring at room temperature for 4 h. Green needle-shaped crystals suitable for X-ray diffraction were obtained by slow evaporation from acetonitrile over three days.

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.
