The title complex, {[Cu2(N3)4(C6H16N2)2][Cu(N3)2(C6H16N2)]}n, consists of an end-on azide-bridged dinuclear copper(II) complex and an end-to-end azide-bridged polynuclear copper(II) complex. Each Cu atom is five-coordinated by two N atoms of N,N-diethylethane-1,2-diamine and by three N atoms from three azide ligands, forming a slightly distorted square-pyramidal coordination environment.

N,N-Diethylethane-1,2-diamine (0.1 mmol, 11.6 mg), NaN3 (0.2 mmol, 13.0 mg), and Cu(CH3COO)2.H2O (0.1 mmol, 20.0 mg) were dissolved
in a methanol solution (10 ml). The mixture was stirred at room temperature
for 20 min to give a blue solution. The solution was kept in air for about a
week, blue block-shaped crystals were formed at the bottom of the vessel on
slow evaporation of the solvent.
H atoms were placed in idealized positions and constrained to ride on their
parent atoms, with C–H distances in the range 0.96–0.97 Å, N–H distances
of 0.90 Å, and with Uiso(H) set to 1.2Ueq(C,N) and
1.5Ueq(methyl C).

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. |

The azide anion is a versatile ligand that is able to link metal ions with different coordination modes, generating interesting polynuclear complexes (Colacio et al., 2005; Meyer et al., 2005; Sarkar et al., 2004). In this paper, a new azido-bridged copper(II) complex is reported.
The title complex consists of an end-on azido-bridged dinuclear copper(II) molecule (unit 1, Fig. 1) and an end-to-end azido-bridged polynuclear copper(II) molecule (unit 2, Fig. 2). Each Cu atom in unit 1 is in a square pyramidal coordination environment and is five-coordinated by two N atoms of N,N-diethylethane-1,2-diamine, one N atom of a terminal azido ligand, and one N atom of an end-on azido bridge, defining the basal plane, and by one N atom of another end-on azido bridge occupying the apical position. Each Cu atom in unit 2 is in a square pyramidal coordination environment and is five-coordinated by two N atoms of N,N-diethylethane-1,2-diamine, one N atom of a terminal azido ligand, and one N atom of an end-to-end azido bridge, defining the basal plane, and by one N atom of another end-to-end azido bridge occupying the apical position. The significant distortion of the square pyramids is revealed by the apical bond lengths (Cu1—N9 = 2.562 (2) Å, Cu2—N5 = 2.654 (2) Å, Cu3—N20 = 2.446 (2) Å), as well as the bond angles between the apical and basal donor atoms (Table 1).
