(Received 3 April 2010; accepted 7 May 2010; online 19 May 2010)

The asymmetric unit of the title complex, [Ni(C16H32N4)]Br2·2H2O, contains two [Ni(C16H32N4)]2+ cations, four Br− anions and four uncoordinated H2O mol­ecules. The Ni atoms are in a slightly distorted square-planar coordination by the four macrocyclic N atoms, which are almost coplanar [N—N—N—N torsion angles of 2.97 (6) and 3.12 (7)°]. In the crystal, a network of N—H⋯Br, O—H⋯Br and N—H⋯O hydrogen bonds leads to the formation of a chain structure.

Comment top

The structures of several related macrocyclic complexes have been reported (Whimp et al., 1970). The nickel (II) tetraazamacrocyclic complex cation, [Ni(C16H32N4)]2+, has both meso and enantiomeric forms (Warner et al., 1968) and can combine with different anions to form many kinds of structures.

We herein report the crystal structure of a new compound synthesized by the reaction of Ni(NO3)2.6H2O and the complex C18H32N4.2HBr.2H2O. Two similar macrocycles are included in the asymmetric unit, and the crystal structure is stabilized by intermolecular hydrogen bonds. As the two macrocycles are in similar coordination with nickel(II), only one of them will be described. As shown in Fig.1, the NiII atom is coordinated by four N atoms from the tetraazamacrocycle in a square-planar geometry, the average Ni—N(amine) bond distance of 2.0132 (4) Å and Ni—N(imine) bond distance of 1.9899 (4)Å are similar to those previously reported (Szalda et al.,1991). The dihedral "fold" angle between the planes formed by N1, N2, N3 and N1, N3, N4 is 4.343 (1)°. The macrocycle is in the N-meso configuration with the amine hydrogens of N1 and N4 on opposite sides of the macrocycle plane. The combination of [Ni(C16H32N4)]2+with two Br- anions and two isolated H2O established the title compound.

Experimental top

All chemicals were of reagent grade and were used as received without further purification. The precursor complex C18H32N4.2HBr.2H2O was prepared previously. To a 10 ml methanol solution of Ni(NO3)2.6H2O (0.2 mmol, 0.344 g), a 5 ml methanol solution of C18H32N4.2HBr.2H2O (0.2 mmol, 0.0957 g) was added dropwise with stirring. The resulting solution was stirred continuously for about 30 min. Brown crystals suitable for X-ray analysis were obtained by slow evaporation at room temperature over several days.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
