(Received 16 October 2007; accepted 7 November 2007; online 9 January 2008)

In the title compound, [Cd(NO₃)₂(C₂₂H₃₀N₂O₄)], the Cd^II atom is eight-coordinated by two amine N atoms and two O atoms from the 5,6:19,20-dibenzo-1,4,11,14-tetraoxa-8,17-diazacycloeicosane ligand and four O atoms from two nitrate groups. The coordination geometry about Cd is antiprismatic. One nitro O atom is disordered equally over two positions.

Comment top

In the last few decades, the modification of the macrocycles to control and tune the properties of coordinated metal atoms has been the subject of much interest (Meyerstein, 1990; Vicente et al., 2003). We are involved in studies of oxaaza-macrocycles and their metal coordination compounds. In this paper, we report the preparation and crystal structure of the title macrocyclic complex of Cd^II.

In the structure of the title compound, Cd^II is eight-coordinated by two N atoms and two O atoms from ligand L and four O atoms from two nitrate groups. The title compound displays an antiprismatic geometry (Fig. 1). The bond distances and angles around the Cd atom are nomal (Popović et al., 2006).

Experimental top

Ligand L was synthesized according to the reported method (López-Deber et al., 2005). A solution of Cd(NO₃)₂.4H₂O (0.03 g, 0.10 mmol) in 5 ml e thanol was added dropwise to a solution of H₂L (0.039 g, 0.10 mmol) in 6 ml e thanol. After stirring for 30 min, the mixture was filtered. Colorless crystals were obtained by evaporating the filtrate at room temperature (yield 50%).

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.
