Abstract:
A number of bipyridyl compounds containing amide functionalities have been prepared as bridging bipyridyl ligands in coordination networks.  The bridging ability and hydrogen bond donor-acceptor functionality of these compounds in coordination networks has been explored by their inclusion in crystallisation experiments containing a single salt from a variety of d block metal salts, with ethanol and water as the solvent.  The crystal structures of the coordination network polymers of [Cd L2 (H2O)2]2/∞ 2NO3 (L = N,N’-bis(3-pyridylmethyl)urea), [Cu L2 (NO3)2]2/∞ . 2H2O .2EtOH (L = N,N’-bis(3-pyridylmethyl)urea), [Cd L2 (NO3) (H2O)]1/∞ . NO3 . H2O (L = N,N’-bis(4-pyridylmethyl)urea), [Cu L2 (NO3) (H2O)]1/∞ . NO3 . H2O (L = N,N’-bis(4-pyridylmethyl)urea), [Cd3 L4 (H2O)8 (H2O)8 (SO4)2]1/∞ . 4H2O . SO4 (L = N,N’-bis(4-pyridylmethyl)urea), [Cu L (OAc)2]1/∞ (L = N,N’-bis(4-pyridylmethyl)urea), [Cu2 L2 (NO3)4 (BIPY)2 (H2O)3/1/∞ . H2O (L = N,N’-bis(4-pyridylmethyl)isophthalamide), (BIPY = 2,2’-bipyridine) and [Cu L2 2(H2O)]1/∞. 2(H2O) . 2(CIO4)2 (L = N,N’-bis(3-pyridylmethyl)succinamide) are described. Wittig reaction conditions, followed by hydrogenation are used for the preparation of a number of saturated bipyridyl compounds possessing an additional aromatic functionality.  The bridging ability of these ligands has been explored by their inclusion in crystallisation experiments containing a single salt from a variety of d block metal salts, with ethanol and water as the solvent.  The crystal structures of the coordination polymers of [Cd L2 (NO3)2]2/∞ (L = 1,2-bis[2-(3-pyridyl)ethyl]benzene), [Cd L2 (H2O)2 (CIO4)2]2/∞ (L = 1,2-bis[2-(3-pyridyl)ethyl]benzene), [Cu1.5 L2 (NO3) (H2O)2]2/∞ . 2(NO3) . 2.7(H2O) (L = 3,5-bis[2-(4-pyridyl)ethyl]pyridine) and [Cd2 L5 (H2O)4]1/∞ . L . 2H2O . 2EtOH . 4CIO4 (L = 1,4-bis[2-(4-pyridyl)ethyl]benzene) are described.
