Sažetak
Syntheses, as well as chemical and X-ray structural characterization of dichlorobis[ 1-(p-toluenesulfonyl)cytosine] copper(II) (2), its pseudopolymorph containing two methanol molecules 3, dichlorobis[ 1-(p-toluenesulfonyl)cytosine] cadmium(II) (4), 1-methanesulfonylcytosine (6) and its copper complex dichlorobis(1-methanesulfonylcytosine)copper(II) (7) are described. In addition, spectroscopic studies of dichlorobis[ 1-(p-toluenesulfonyl)cytosine] cobalt(II) (5), as well as of dichlorobis(1-mesylcytosine)cadmium(II) (8) are presented. Pseudopolymorphs 2 and 3, as well as their 1-mesylcytosine analogue 7, reveal square-planar coordination spheres, almost ideal in the case of 2, but considerably distorted in the case of 3 and 7. In all cases, the Cu(II) is coordinated by two endocyclic N3 from two ligand molecules and by two chlorines. The analogous coordination sphere was found in complex 4, where Cd(II) lies in the centre of the slightly distorted tetrahedron formed by two endocyclic N3 and by two chlorine atoms.
