摘要：
Reactions of 2,2'-dipyridylamine (dpyam) with cadmium halides yield crystals of [Cd(dpyam)(H2O)Cl-2] (1), [Cd(dpyam)Br-2] (2), and [Cd(dpyam)I-2] (3). With CuCl2 and KCN a complex [Cu(dpyam)CN]H2O (4) is obtained. Depending on the size of the halide ions the coordination changes from octahedral in 1 to trigonal bipyramidal in 2 and tetrahedral in 3. The coordination in 4 is trigonal. Due to the geometric strain imposed by the ligand all coordination polyhedra show significant distortions. 1 and 2 form dimers by halide bridges. With the exception of 3 all compounds form "supramolecular" structures via hydrogen bonds, e.g. chains or networks.
