The title compound (C5H14NO)4[Cu2(CH3COO)4Cl2]Cl2, consists of a pair of CuII ions bridged by four acetate groups, resulting in a Cu2(CH3COO)4 unit, four (3-hydroxy­prop­yl)dimethyl­ammonium cations (two crystallographically independent pairs) and two chloride anions. The Cu atoms at both termini are bonded to chloride anions. The latter are hydrogen bonded to one of the two pairs of crystallographically independent (3-hydroxy­prop­yl)dimethyl­ammonium cations. The Cu2(CH3COO)4 unit is located on a crystallographic inversion center, and the geometry around each metal center is close to octa­hedral. The Cl—Cu—Cu angles are nearly linear [177.48 (2)°] and the Cu—O bond lengths are in the range 1.9712 (18)–1.9809 (19) Å. The Cu⋯Cu separation between the two acetate-bridged CuII centers is 2.6793 (8) Å. The packing of the crystal structure is dominated by N—H⋯Cl hydrogen bonding between the ammonium groups and the chloride anions, as well as by O—H⋯O and O—H⋯Cl hydrogen bonds. One of the 3-hydroxypropyldimethylammonium cations shows orientational disorder with an occupancy ratio of 0.812 (4): 0.188 (4).

Comment top

In relation to our previous work on the structural chemistry of copper complexes (Shahid, Mazhar, Helliwell et al., 2008) we described here the crystal structure of the title compound. It consists of a centrosymmetric acetate bridged Cu2(CH3COO)4 moiety with chloride anions at both termini, four (dimethylammonium)propanol cations and two chloride anions.

In the title compound (Fig. 1) the two metal centers are related by a crystallographic inversion cernter; each has a coordination environment close to octahedral, with a CuO4CuCl set of ligating atoms, composed of four oxygen atoms of four bridging acetate groups, a terminal chloride atom and the second copper atom. The equatorial plane is made up of atoms O1, O2, O3 and O4 of the four bridging acetate ligands connecting both copper atoms, while the chloride ion Cl1 links to Cu1 in the axial position of the octahedron. The inversion related copper atoms are linked by a Cu—Cu bond thus completing the octahedral coordination of each copper center. The trans angles in the equatorial plane deviate slightly from the ideal value of 180°, and the Cu—O bond lengths fall in the range of 1.9712 (18)–1.9809 (19) Å. These values are in good agreement with the values reported for Cu2(CH3COO)4(H2O)2 (Van Niekerk & Schoening,1953), and in more accurate structure determinations of this compound (Meester et al., 1973; Nieger, 2001; Ferguson & Glidewell, 2003; Steed et al., 1998; Vives et al., 2003; Golzar Hossain, 2007; Mahmoudkhani & Langer, 1998) and for similar complexes (Shahid, Mazhar, Malik et al., 2008; Shahid et al., 2009; Zhang et al., 2004). They indicate a slightly distorted octahedral geometry around both copper centers in the complex. The length of the central Cu—Cu bond of 2.6793 (8) Å is significantly longer than the value reported for dinuclear copper (II) acetate monohydrate by X-ray diffraction (see above) as well as by neutron diffraction analysis (Brown & Chidambaram, 1973), but it does agree well with that of the only other structurally determined tetra-µ-acetato-k8O:O'-dicuprate(II) with two terminal chloride ligands, which was reported by Ackermann et al. (2000) as 2.687 Å.

In the crystal structure the terminal chlorides are hydrogen bonded to one of crystallography independent (dimethylammonium)propanol cations (Fig. 2 and Table 1). The other crystallographically indepenent dimethyl(3-hydroxypropyl) ammonium ion is disordered over two positions, with both moieties being approximate mirror images of each other (see refinement section for details). This disorder results in a significantlty different hydrogen bonding environment for the two moieties. The dominant orientation exhibits an N—H···Cl hydrogen bond of ca 2.15 Å between H1 and Cl2. The less prevalent moiety shows a much weaker bond with an N1B—H1B···Cl1i bond distance of 2.53 Å (symmetry operator (i): -x + 1, y - 1/2, -z + 3/2). The packing of the crystal structure is dominated by hydrogen bonding between the ammonium N—H units and the chloride (Cl2) anions, as well as O—H···O and O—H···Cl hydrogen bonds (Fig. 3 and Table 1).

Experimental top

N,N-Dimethylaminopropanol (dmapH) (0.76 g, 7.43 mmol) and acetic acid (0.45 g, 7.43 mmol) were added to a stirred suspension of Cu(CH3COO)2.H2O (0.74 g, 3.72 mmol) and anhydrous CuCl2 (0.50 g, 3.72 mmol) in 30 ml tetrahydrofuran (THF). After two hours stirring, the mixture was vacuum evaporated to dryness and the solid was redissolved in a minimum amount of THF to give green block-shaped crystals at room temperature after 10 days.

Refinement top

The crystal under investigation was found to be non-merohedrally twinned. The orientation matrices for the two components were identified using the program Cell Now (Sheldrick, 2005). The twin operation was found to be a two fold rotation around the a axis. The two components were integrated using Saint implemented in Apex2, resulting in a total of 19624 reflections. 1995 reflections (1332 unique ones) involved component 1 only (mean I/sigma = 16.7), 1945 reflections (1310 unique ones) involved component 2 only (mean I/sigma = 5.6), and 15684 reflections (6317 unique ones) involved both components (mean I/sigma = 10.8). The exact twin matrix identified by the integration program was found to be 1.00091 0.00101 0.00457, 0.00080 - 1.00000 - 0.00090, -0.39803 0.00179 - 1.00091.

The data were corrected for absorption using Twinabs, and the structure was solved using direct methods with only the non-overlapping reflections of component 1. The structure was refined using the hklf 5 routine with all reflections of component 1 (including the overlapping ones) below a d-spacing threshold of 3/4, resulting in a BASF value of 0.118 (6). The Rint value given is for all reflections before the cutoff at d = 0.75 and is based on agreement between observed single and composite intensities and those calculated from refined unique intensities and twin fractions [Twinabs (Sheldrick, 2007)].

One of the 3-dimethylamine-propan-1-ol ligands shows orientational disorder with an occupancy ratio of 0.812 (4) to 0.188 (4), with both moieties being approximate mirror images of each other. Atoms N1, C5 and C6, which significantely overlap with their equivalent counterparts, were constrained to have the same ADPs as their equivalent partners in the minor moiety. No restraints were applied for non-hydrogen atoms.

The hydroxyl hydrogen atom bonded to O5 did not show any visible disorder [despite being part of the disordered dimethyl(3-hydroxypropyl)ammonium group] and was freely refined with an O—H distance restraint of 0.837 (19) Å. The C—H and N—H atoms were placed in calculated positions and treated as riding atoms: N-H = 0.93 Å, C-H = 0.98 - 0.99 Å, with Uiso(H) = k × Ueq(parent atom), where k is 1.2 for C-methylene and N-ammonium, and 1.5 for C-methyl and O-hydroxyl.

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.
