A solution of ZnBr2 0.0207 g (0.1 mmol) in CH3CN (5 ml) was added to a solution of tacntp (0.1 mmol) (tacntp = 1,4,7-triazacyclononane-1,4,7-tripropionate) in CH3CN (15 ml). The reaction mixture was stirred at room temperature for 30 min. Then (C4H9)4N (0.1 mmol) was added to the solution. The reaction mixture was continuously stirred for 2 h at room temperature. Several months later, crystals suitable for X-ray diffraction were obtained by slow evaporation of the filtrate. Calculated for [(C4H9)4N]2[ZnBr4]: C 44.14, H 8.28, N 3.22, Br 32.65%; found: C 44.15, H 8.27, N3.24, Br 32.67%.
H atoms were placed in calculated positions with C—H = 0.96–0.97 Å and were included in the riding-motion approximation with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms. In one of the cation molecules three C atoms are disordered over two sites with refined occupancies of 0.500 (16). The C—C bonds distances of the disorder components were restained to 1.54 (1) Å.
In recent years, the crystal engineering of materials containing Zn(II) has become an intensively active field due to not only their structural diversity, but also their promising applications in the fields of catalysis, (Wang, Zhuang et al., 2007) medicine, magnetism, photochemistry, fluorescence (Yu et al., 2007; Zhang et al., 2007) and electrical chemistry (Liu et al., 2007; Tian et al., 2007; Wang, Moorefield et al., 2007). With this in mind, we have synthesized the title complex and its crystal structure is determined herein. The ZnII ion is coordinated by four Br atoms in a slightly distorted tetrhedral geometry. The asymmetric unit of (I) is shown in Fig. 1.
Some research related to zinc(II) compounds has already been published (Wang, Zhuang et al., 2007; Yu et al., 2007; Zhang et al., 2007; Liu et al., 2007; Tian et al., 2007; Wang, Moorefield et al., 2007).

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. |

In recent years, the crystal engineering of materials containing Zn(II) has become an intensively active field due to not only their structural diversity, but also their promising applications in the fields of catalysis, (Wang, Zhuang et al., 2007) medicine, magnetism, photochemistry, fluorescence (Yu et al., 2007; Zhang et al., 2007) and electrical chemistry (Liu et al., 2007; Tian et al., 2007; Wang, Moorefield et al., 2007). With this in mind, we have synthesized the title complex and its crystal structure is determined herein. The ZnII ion is coordinated by four Br atoms in a slightly distorted tetrhedral geometry. The asymmetric unit of (I) is shown in Fig. 1.
