Self-assembly, crystal structure, and spectroscopy properties of two new complexes with 1,10-phenanthroline-5,6-dione and SCN ligands

Abstract

Two new complexes [Co(Pdon)(SCN) 2 (H 2 O) 2 ] (I) and [Hg(Pdon) 2 Br 2 ] (II) (Pdon = 1,10 phenanthroline 5,6 dione) have been synthesized and characterized by element analysis, IR and single crystal X ray diffraction (CIF files CCDC nos. 793904 (I) and 783209 (II)). Compounds I and II are mono nuclear complexes obtained by the self assembly of Pdon, SCNand metal ion Co 2+ and Hg 2+ , which are further in close contacted forming a two dimensional supramolecular framework via O-H⋅⋅⋅S and O-H⋅⋅⋅O hydrogen bonding interactions interactions between adjacent molecules.
