Abstract

The crystal structure of CuCl2L·1/2 C2H5OH has been redetermined, where L=4-aminobenzophenone. C14H14Cl2CuNO1.5,Mr=354.5, monoclinic, P21/c,a=8.206(1),b=6.196(2),c=29.917 (7) Å, β=92.91°,V=1521.8(6) Å3,Z=4,Dx=1.55 g cm−3, λ(MoKα)=0.71069Å, μ=17.9 cm−1,F(000)=720,T=295K. The 1984 unique reflections (20<45°), of which 1635 had |Fo|≥3σ (Fo), refined to a finalR of 0.042 andwR=0.049 for the 3σ data set. The structure is disordered at room temperature with the ethanol molecules, present at half-occupancy, coordinating to only one half of the Cu(II) ions. The structure is comprised of two types of chains which run parallel tob. One type of chain consists of stacks of CuCl2L(C2H5OH) monomer units, which yield a 4+2 coordination geometry for each Cu atom in the chains. The second type of chains has stacks of binuclear Cu2Cl4N2 species with a 4+1 coordination exhibited by each Cu. The location and orientation of the L ligands appear to be identical in the two stacks. Intermolecular hydrogen bonding between L ligands in adjacent stacks leave space for only one ethanol molecule per two ligands.
