Received: 10 September 2010; in revised form: 18 October 2010 / Accepted: 25 October 2010 / Published: 15 November 2010 Abstract: Four new 2,2’-bipyridine and 1,10-phenanthroline complexes, namely - - [Mn(phenca) ]·(H O) (1), [Cu (phen) (OH ) (H O) ](DMF) (ClO ) (H O) (2), 2 2 2 4 4 4 2 2 4 4 4 2 [Cu (2,2-bipy) (C O 2-)(H O) (NO ) ] (3) and [Cu(2,2-bipy) (ClO -)](ClO -) (4) 2 2 2 4 2 2 3 2 2 4 4 (2,2’-bpy = 2,2’-bipyridine, Hphenca = 1,10-phenanthroline-2-carboxylic acid) have been synthesized by a hydrothermal reaction. The products were characterized by elemental analysis, infrared spectroscopy and X-ray crystal diffraction. While strong hydrogen bonds
