The title compound, [Cu(C
12H
16N
3O
3)Cl]
n, is a chloride-bridged polymeric copper(II) complex. The Cu
II atom is five-coordinate in a square-pyramidal geometry, with one O and two N atoms of the Schiff base ligand and one Cl atom defining the basal plane [Cu
Cl = 2.2703 (8) Å] and a symmetry-related Cl atom occupying the apical position [2.8531 (9) Å]. The chloride-bridged polymeric chain runs along the
b axis.

5-Nitrosalicylaldehyde (0.1 mmol, 16.5 mg), N-isopropylethane-1,2-diamine
(0.1 mmol, 10.2 mg), and copper chloride dihydrate (0.1 mmol, 17.0 mg) were
dissolved in a methanol solution (10 ml). The mixture was stirred at room
temperature for 30 min, giving a clear blue solution. Crystals of the title
compound were formed by slow evaporation of the solvent over a week at room
temperature.
Atom H3A was located from a difference Fourier map and refined isotropically,
with the N—H distance restrained to 0.90 (1) Å, and with the
Uiso(H) value fixed at 0.08 Å2. The remaining H atoms were placed
in geometrically idealized positions and constrained to ride on their parent
atoms with C–H distances in the range 0.93–0.97 Å, and with
Uiso(H) = 1.2 or 1.5Ueq(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. |

Recently, we have reported a thiocyanate coordinated zinc(II) complex (Ye & You, 2007a) and a thiocyanate coordinated copper(II) complex (Ye & You, 2007b). As an extension of the work on the crystal structures of such complexes, we report herein the crystal structure of the title compound.
The title compound is a chloride-bridged polynuclear copper(II) complex (Fig. 1). The CuII atom is five-coordinated in a square-pyramidal geometry, with one O and two N atoms of the Schiff base ligand and one Cl atom defining the basal plane (Cu···Cl = 2.2703 (8) Å), and a symmetry-related Cl atom occupying the apical position (2.8531 (9) Å). Selected bond distances and angles within the coordination sphere of the metal atom are given in Table 1. The crystal structure is stabilized by N—H···O and and C—H···O hydrogen bonds (Table 2).
