Abstract
THE tridentate ligand 1,3-bis(2′-pyridyl)-2,3-diaza-1-propene, (paphy), when reacted with cobalt(II) chloride in ethanolic solution, yields several products. Two of these complexes are formulated as Co(paphy)Cl2 : one (designated α-) forms red plates and the other (β-) dark green needles. The β-isomer may readily be converted to the α-compound by heating in ethanolic medium.
