H atoms were placed in geometrically idealized positions and constrained to ride on their parent atom with C—H distances of 0.99 (CH3), 0.98 (CH2), and 0.92 (NH2) Å with Uiso(H) = 1.2Ueq(C), (CH2, NH2) and 1.5Ueq(C) (CH3).
The room temperature structure of (DEA)2CuCl4 was originally reported by Simonsen (Harlow & Simonsen, 1976), but full details were never published. Nevertheless, the compound has been the subject of several investigations, including thermochromism (Willett et al., 1974; Bloomquist & Willett, 1982; Kapustianik et al., 1994) and magnetism (Landee et al., 1978). The compound undergoes a first order phase transition at 323 K, changing color from green to yellow. In the high temperature phase, there are two independent CuCl42- anions, both with compressed tetrahedral geometry (Bloomquist & Willett, 1982) in the asymmetric unit. The unique feature of both the room and low temperature structures is the existence of three crystallographic independent CuCl42- anions in the asymmetric unit, each with different geometries, ranging from essentially square planar coordination to compressed tetrahedral geometry.
The stucture of the title compound, (I), is shown below. Dimensions are available in the archived CIF. The distortions of the CuCl42- anions may be characterized by the average of the two larger trans Cl—Cu—Cl angles. For the square planar anion (containing Cu2), the average trans angle is 178.6°. In the anions containing Cu1 and Cu3, these values are 161.9° and 146.2 ° respectively, indicating increasing distortion towards tetrahedral geometry. The differences in distortion can be traced to the hydrogen bonding interactions, with stronger hydrogen bonding interactions favoring the square planar geometry over the compressed tetrahedral geometry (Halvorson et al., 1990). All three CuCl42- anions participate in four bifurcated N—H···Cl hydrogen bonds. However, the nature of the bonding interactions is different for the three anions. For the square planar anion, all four of the bifurcated hydrogen bonds are nearly symmetric. In contrast, the anion containing Cu1 has two nearly symmetric hydrogen bonds and two very asymmetric ones, while for the anion closest to tetrahedral geometry, all of the hydrogen bonds are very asymmetric. These hydrogen bonds tie the anions together into layers that lie parallel to the (101) planes, producing short Cl···Cl contacts, that are presumably responsible for the observed two-dimensional magnetic behavior (Landee et al., 1978).

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 room temperature structure of (DEA)2CuCl4 was originally reported by Simonsen (Harlow & Simonsen, 1976), but full details were never published. Nevertheless, the compound has been the subject of several investigations, including thermochromism (Willett et al., 1974; Bloomquist & Willett, 1982; Kapustianik et al., 1994) and magnetism (Landee et al., 1978). The compound undergoes a first order phase transition at 323 K, changing color from green to yellow. In the high temperature phase, there are two independent CuCl42- anions, both with compressed tetrahedral geometry (Bloomquist & Willett, 1982) in the asymmetric unit. The unique feature of both the room and low temperature structures is the existence of three crystallographic independent CuCl42- anions in the asymmetric unit, each with different geometries, ranging from essentially square planar coordination to compressed tetrahedral geometry.
The stucture of the title compound, (I), is shown below. Dimensions are available in the archived CIF. The distortions of the CuCl42- anions may be characterized by the average of the two larger trans Cl—Cu—Cl angles. For the square planar anion (containing Cu2), the average trans angle is 178.6°. In the anions containing Cu1 and Cu3, these values are 161.9° and 146.2 ° respectively, indicating increasing distortion towards tetrahedral geometry. The differences in distortion can be traced to the hydrogen bonding interactions, with stronger hydrogen bonding interactions favoring the square planar geometry over the compressed tetrahedral geometry (Halvorson et al., 1990). All three CuCl42- anions participate in four bifurcated N—H···Cl hydrogen bonds. However, the nature of the bonding interactions is different for the three anions. For the square planar anion, all four of the bifurcated hydrogen bonds are nearly symmetric. In contrast, the anion containing Cu1 has two nearly symmetric hydrogen bonds and two very asymmetric ones, while for the anion closest to tetrahedral geometry, all of the hydrogen bonds are very asymmetric. These hydrogen bonds tie the anions together into layers that lie parallel to the (101) planes, producing short Cl···Cl contacts, that are presumably responsible for the observed two-dimensional magnetic behavior (Landee et al., 1978).
