Abstract
The crystal structure of the title compound has been determined from three-dimensional, single crystal X-ray diffraction data. [Cu2Cl2(C13H12NO2)2]·2H2O crystallizes in the orthorhombic space group P212121 with lattice constants,a=11.866(2),b=13.555(3),c=17.380(3) Å. Final full-matrix least-squares refinement of 3735 unique reflections yieldedR=0.054. The structure consists of dimeric C26H24Cl2Cu2N2O4 molecules and water molecules connected with the dimeric molecules by a hydrogen bond system. Both of the copper(II) centers are five-coordinated by twotrans oxygen atoms and one nitrogen atom from one ligand molecule and two chloride ions. The geometry at each copper(II) center is best described as distorted tetragonal pyramidal. The apical Cu1−Cl2 and Cu2−C11 distances are 2.747(2) and 2.938(3)Å, respectively. The Cu...Cu separation is 3.496(1)Å. The comparison with previously reported crystal structure of [Cu2Cl2 (C13H12NO2)2]·1/2H2O is given.
