Dehydrogenative coupling of phenanthroline under hydrothermal conditions:: crystal structure of a novel layered vanadate complex constructed of 4,8,10-net sheets:: [(2,2′-biphen)Co]V3O8.5

2,2'-Biphenanthroline (2,21-biphen) formed from 1,10-phe-nanthroline when a new two-dimensional layered vanadium oxide metal coordination complex, [(2,21-biphen)CO]V3O8.5, which contains novel 4,8,10-net sheets, was hydrothermally synthesized.
