Nicotinamide was employed as a supramolecular reagent in the synthesis of six new copper(II) bromo-, iodo-, fluoro- and dibromobenzoate complexes. Structures of [Cu(2-Brbz)
The crystal structures of the title compounds, [Mn(phen) 2 Cl 2 ] (I) and [Mn(bipy) 2 Cl 2 ] (II), have been determined at 150 K. The manganese atoms in both compounds are coordinated by four pyridine nitrogen atoms from two 1,10-phenanthroline or 4,4´-bipyridine ligands and two chloride anions, resulting in a distorted cis-MnN 4 Cl 2 octahedral geometry. Both complexes are connected through C-H···Cl hydrogen bonds into frameworks. The π-π stacking interactions are observed in crystal structure of both ones.
The synthesis, crystal structures and spectroscopy of [{Cu(2anion, benzim = benzimidazole, 4-pyme = 4-pyridylmethanol, nia = nicotinamide, pydca = 3,4-pyridinedicarboxamide, mna = N-methylnicotinamide) are reported. The complexes under study were characterized by electronic, IR and EPR spectroscopy, and single-crystal X-ray structure analysis. The complexes form one-dimensional or two-dimensional brick-wall like coordination polymers. The coordination environments around the copper atoms of complexes 1-3 and 5 are distorted tetragonal pyramidal. The copper atom in complex 4 has tetragonalbipyramidal coordination. Four different coordination modes of adipate ligands in the studied copper(II) complexes were observed. The coordination polymers of the complexes are connected through hydrogen bonds into 2-D or 3-D supramolecular frameworks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
