To a stired solution of tris(N-methylbenzimidazol-2-ylmethyl)amine (0.0899 g, 0.2 mmol) in hot MeOH (10 ml) was added Cu(ClO4)2(H2O)6 (0.0741 g, 0.2 mmol), followed by a solution of Na(2-Methacrylate) (0.0216 g, 0.2 mmol) in MeOH (5 ml). A Blue-green crystalline product formed rapidly. The precipitate was filtered off, washed with MeOH and absolute Et2O, and dried in vacuo. The dried precipitate was dissolved in DMF to a blue-green solution that was allowed to evaporate at room temperature. Blue-green crystals suitable for X-ray diffraction studies were obtained after three weeks. Yield, 0.0904 g (53%). (found: C, 52.37; H, 5.32; N,14.74; Cu, 7.71. Calcd. for C37H47ClCuN9O8.50: C, 52.11; H, 5.55; N, 14.78; Cu, 7.45%)
Very large displacement ellipsoids indicated that the 2-methacrylate ligand was disordered over two sites and the intemolecular contacts require the disorder components to be equal over two sites. All H atoms were found in difference electron maps and were subsequently refined in a riding-model approximation with C—H distances ranging from 0.95 to 0.99 Å, and Uiso(H) = 1.2Ueq(C) of the carrier atom, The H atoms of the partial occupancy O atom [O7] were placed in positions which give suitable hydrogen bonding interactions and were refined as riding with Uiso(H) = 1.5Ueq(O).
The asymmetric unit of the title compound, (Fig. 1), consists of a discrete [Cu(Mentb)(2-Methacrylate)] cation [Mentb is tris(N-methylbenzimidazol-2-ylmethyl)amine], a perchlorate anion, 2 DMF molecules and a half occupancy water molecule. The 2-Methacrylate is disordered over two sites with equal occupanancies. The copper ion is five-coordinate with a N4O ligand set. The Mentb ligand acts as a tetradentate N-donor, and an O atom of carboxylate group of the 2-methacrylate ligand completes the coordination. The coordination geometry of the CuII ion may best be described as distorted trigonal bipyramidal (tau = 0.46), with approximate site symmetry C3. The parameter tau (Youngme et al., 20070 is defined as (beta - alpha)/60 [where beta = O1—Cu—N7, alpha = N5—Cu—N3] and its value varies from 0 (in regular square-based pyramidal) to 1 (in regular trigonal bipyramidal). This geometry is assumed by the CuII ion to relieve the steric crowding. The equatorial plane is occupied by three N atoms of three benzimidazolyl groups, while the CuII atom protrudes towards O1 and is 0.343 (3) Å from the plane of atoms N1/N3/N5. The axial positions are occupyied by N7 and O1, with Cu—N7 = 2.177 (3) A, Cu—O1 = 1.925 (3) Å and O1—Cu—N7 = 176.25 (11)°. The three benzimidazole ring arms of the Mentb ligand form a cone-shaped cavity. The angles N3—Cu—N1, N5—Cu—N1 and N5—Cu—N3 are 89.51 (12), 110.77 (12) and 148.74 (13)° respectively. The angles N7—Cu—N1 = 78.62 (12), N7—Cu—N3 = 82.00 (11) and N7—Cu—N5 = 79.21 (11)°, are all ca 10 ° less than the ideal value of 90°, are imposed by the geometry of the Mentb ligand. The distance between the CuII ion and atom O2 is 2.886 (3) Å, and hence O2 does not form a coordination bond. The bond angles and distances in the Mentb and 2-Methacrylate ligands are within the normal ranges (Allen et al., 1987). In the crystal structure, the solvent water molecule forms weak O—H···O hydrogen bonds.

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. |

The asymmetric unit of the title compound, (Fig. 1), consists of a discrete [Cu(Mentb)(2-Methacrylate)] cation [Mentb is tris(N-methylbenzimidazol-2-ylmethyl)amine], a perchlorate anion, 2 DMF molecules and a half occupancy water molecule. The 2-Methacrylate is disordered over two sites with equal occupanancies. The copper ion is five-coordinate with a N4O ligand set. The Mentb ligand acts as a tetradentate N-donor, and an O atom of carboxylate group of the 2-methacrylate ligand completes the coordination. The coordination geometry of the CuII ion may best be described as distorted trigonal bipyramidal (tau = 0.46), with approximate site symmetry C3. The parameter tau (Youngme et al., 20070 is defined as (beta - alpha)/60 [where beta = O1—Cu—N7, alpha = N5—Cu—N3] and its value varies from 0 (in regular square-based pyramidal) to 1 (in regular trigonal bipyramidal). This geometry is assumed by the CuII ion to relieve the steric crowding. The equatorial plane is occupied by three N atoms of three benzimidazolyl groups, while the CuII atom protrudes towards O1 and is 0.343 (3) Å from the plane of atoms N1/N3/N5. The axial positions are occupyied by N7 and O1, with Cu—N7 = 2.177 (3) A, Cu—O1 = 1.925 (3) Å and O1—Cu—N7 = 176.25 (11)°. The three benzimidazole ring arms of the Mentb ligand form a cone-shaped cavity. The angles N3—Cu—N1, N5—Cu—N1 and N5—Cu—N3 are 89.51 (12), 110.77 (12) and 148.74 (13)° respectively. The angles N7—Cu—N1 = 78.62 (12), N7—Cu—N3 = 82.00 (11) and N7—Cu—N5 = 79.21 (11)°, are all ca 10 ° less than the ideal value of 90°, are imposed by the geometry of the Mentb ligand. The distance between the CuII ion and atom O2 is 2.886 (3) Å, and hence O2 does not form a coordination bond. The bond angles and distances in the Mentb and 2-Methacrylate ligands are within the normal ranges (Allen et al., 1987). In the crystal structure, the solvent water molecule forms weak O—H···O hydrogen bonds.
