The title complex was prepared by the direct combination of 1:1 molar equivalents of cyclen, Zn(NO3)2 and KI in ethanol at room temperature for two hours. Then the solution was filtered off and placed directly in the air to evapore the solvent. Single crystals of the title compound suitable for structure analysis were obtained fromn the solution after two weeks.
H atoms were positioned geometrically and refined using a riding model with C—H = 0.97 Å, N—H = 0.91 Å, and with Uiso(H) = 1.2 times Ueq(C or N).
The 1,4,7,10-tetraazacyclododecane (cyclen) is a multipotent ligand which has been used in chemistry, biology and many other fields not only due to its excellent coordination properties but also because of the interesting characteristics of its with metal complexes (Guo et al., 1999). Previously accumulated studies about the intrinsic chemical properties of Zn2+ can be finely tuned by complexation with macrocyclic polyamines such as 1,5,9-triazacyclododecane and 1,4,7,10-tetraazacyclododecane (Kimura et al., 2004). Kimura et al. and others also have investigated the coordination of imides and phosphates to Zn(II)-cyclen complexes in great detail (Kimura et al., 1993; Kimura et al.,1997).
In this paper, we report the crystal structure of a novel Zn(II)-cyclen complex composed of a iodo-(1,4,7,10-tetraazacyclododecane)-zinc(II) cation and a triiodine anion as the counter anion. The asymmetric unit of the title compound is presented in Figure 1. In the cation each zinc atom is coordinated by four nitrogen atoms of the cyclen and one iodo ligand (Fig.1). Weak intermolecular C—H···I interactions seem to be effective in the stabilization of the whole crystal structure in which two neighboring cations are linked into a dimeric unit (C4—H4b···I1i; i: 1 - x,1 - y,1 - z) (Fig. 2). Additional weak intermolecular C—H···I interactions (C7—H7a···I4; C5—H5b···I4ii; ii: -x,1 - y,-z) link all of the dimers into a linear one-dimensional supramolecular structure (Fig. 2).

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 1,4,7,10-tetraazacyclododecane (cyclen) is a multipotent ligand which has been used in chemistry, biology and many other fields not only due to its excellent coordination properties but also because of the interesting characteristics of its with metal complexes (Guo et al., 1999). Previously accumulated studies about the intrinsic chemical properties of Zn2+ can be finely tuned by complexation with macrocyclic polyamines such as 1,5,9-triazacyclododecane and 1,4,7,10-tetraazacyclododecane (Kimura et al., 2004). Kimura et al. and others also have investigated the coordination of imides and phosphates to Zn(II)-cyclen complexes in great detail (Kimura et al., 1993; Kimura et al.,1997).
In this paper, we report the crystal structure of a novel Zn(II)-cyclen complex composed of a iodo-(1,4,7,10-tetraazacyclododecane)-zinc(II) cation and a triiodine anion as the counter anion. The asymmetric unit of the title compound is presented in Figure 1. In the cation each zinc atom is coordinated by four nitrogen atoms of the cyclen and one iodo ligand (Fig.1). Weak intermolecular C—H···I interactions seem to be effective in the stabilization of the whole crystal structure in which two neighboring cations are linked into a dimeric unit (C4—H4b···I1i; i: 1 - x,1 - y,1 - z) (Fig. 2). Additional weak intermolecular C—H···I interactions (C7—H7a···I4; C5—H5b···I4ii; ii: -x,1 - y,-z) link all of the dimers into a linear one-dimensional supramolecular structure (Fig. 2).
