The Cu atom in the title compound, [Cu(NO3)(C9H21N3)]ClO4, is coordinated facially by the tridentate triazacyclononane ligand, and also by a chelating nitrate anion. In addition, the copper makes a sixth much longer interaction [2.828 (3) Å] with an O atom of the perchlorate anion.

Blue crystals of the title complex were obtained by slow diffusion of a
methanolic solution (15 ml) of sodium perchlorate (0.2 g) into a methanolic
solution (15 ml) of copper nitrate (0.4 g) and
1,4,7-trimethyl-1,4,7-triazacyclononane (0.28 g).
The largest residual electron-density peak is 0.84 Å from C4.

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. |

Recent work has reported the synthesis of M8(CN)12 cubes in which the formation of the cubes is directed by the occupation of three facial coordination sites of the octahedral metal ions by `capping' ligands, such as cyclopentadiene or triazacyclononane derivatives (Heinrich et al., 1998; Klausmeyer et al., 1998, 1999). In such work, precursor complexes which contain one such tridentate `capping' ligand and three further accessible coordination sites are important components in the reaction design. We report here the structure of one such complex.
The structure of the title complex, (I), is shown in Fig. 1. It consists of a Cu atom coordinated facially by the tridentate 1,4,7-trimethyl-1,4,7-triazacyclononane ligand, and also by a chelating nitrate anion (Table 1). Although the Cu atom is nominally five-coordinate, it also makes a weak interaction [2.828 (3) Å] with an O atom of the perchlorate anion. An unusual feature of this simple complex is the presence of two different types of counter-anion. This is likely due to crystal packing effects; both the nitrate and the perchlorate participate in a number of weak intermolecular C—H···O contacts with the organic ligands (Table 2).
