Abstract top

The title compound, [Ni(C8H5O4)(C16H36N4)]ClO4·H2O, has the NiII atom in a distorted octahedral geometry, surrounded by coordination by four N atoms of the 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane ligand in a folded configuration, and two carboxylate O atoms of the 2-carboxybenzoate ligand in cis positions. The complex cation, the disordered perchlorate anion [occupancies 0.639 (8):0.361 (8)] and uncoordinated water molecules engage in N-H...O and O-H...O hydrogen bonding, forming a layer structure parallel to (010).

Comment top

Recently, many helical structures were constructed through the coordination interactions, and helical polymers constructed via hydrogen bonding are still rare, and only a few cases have been reported (Khatua et al., 2006; Lonnon et al., 2006; Telfer & Kuroda, 2005). Then we employ racemic nickel(II) complex and phthalic acid as building blocks to construct helical structure, but the result of experiment indicate a racemic complex of [Ni(rac-L)(Hpt)(ClO4)].H2O (pt=phthalic acid) is obtained.

In the asymmetric unit of (I), contains one [Ni(rac-L)(Hpt)]+ cation, one [ClO4]- anion and one water molecule. The [ClO4]- anion is disordered over two symmetry related sites with 50% occupancy. As illustrated in Fig.1, The six-coordinated Ni2+ of [Ni(rac-L)(Hpt)]+ cation displays a distorted octahedral geometry by coordination with four N atoms of macrocyclic ligand L in a folded configuration, and two carboxylate oxygen atoms of phthalic acid in cis-position. Neighbouring cations, anions and water molecule are discrete, connected to each other through intermolecular hydrogen bond.

Experimental top

Phthalic acid (H2pt, 0.166 g, 1 mmol) was mixed with NaOH (0.040 g, 1 mmol) dissolved in 10 ml of water. To this solution was added [Ni(rac-L)](ClO4)2 (0.541 g, 1 mmol) dissolved in a minimum amount of CH3CN. The solution was left to stand at room temperature and blue crystals formed after several weeks.

Refinement top

H atoms bound to C, O and N atoms were positioned geometrically and refined using the riding model, and with C—H = 0.95 to 1.00 Å, O—H = 0.84 Å and N—H = 0.93 Å, and with U(H) set to 1.2 to 1.5 Ueq(C, O, N).

H atoms attached to O (water) atoms were located in difference Fourier maps and condtrained to ride on their carrier atoms, with O—H distances in the range 0.86 Å, and with Uiso (H) = 1.2 times Ueq (O).

Disorder in the [ClO4]- anion required the Cl–O distance to be restrained to 1.44±0.01 Å and the O–O distance to 2.35±0.02 Å.

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.
