On August 18, 2014, Hurley, Nicholas J.; Hayward, John J.; Rawson, Jeremy M.; Murrie, Mark; Pilkington, Melanie published an article.SDS of cas: 75449-26-2 The title of the article was Exploring the Coordination Chemistry of 3,3′-Di(picolinamoyl)-2,2′-bipyridine: One Ligand, Multiple Nuclearities. And the article contained the following:
The syntheses, structures, and magnetic properties of three new coordination complexes, tetranuclear [Zn2L3(OAc)(OMe)]2·3MeOH·H2O (3), trinuclear [Ni3(L3)3]·6H2O (4), and a 1-dimensional chain {[Cu2L3(OAc)2]2·H2O}n (6), of a polydentate, doubly deprotonated, disubstituted bipyridine ligand, 3,3′-bis(picolinamido)-2,2′-bipyridine, [L3]2-, are reported. The x-ray crystal structures demonstrate that the ditopic ligand provides a flexible N3 donor set for transition metal ions where each binding pocket shifts from fac to intermediate fac/mer to the mer isomer affording a Ni3 triangle, a Zn4 tetramer, and a 1-dimensional Cu(II) polymer, resp. This variation in coordination preference is rationalized with the aim of designing future ligands with controlled coordination modes. Magnetic susceptibility studies on 4 reveal it belongs to the rare family of ferromagnetically coupled [Ni3] clusters. In contrast, magnetic studies of the 1-dimensional chain 6 reveal weak antiferromagnetic interactions due to the poor orbital overlap of the singly occupied Cu(II) dx2-y2 orbitals with the 1-atom bridge that connects them along the Jahn-Teller distortion axis. The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).SDS of cas: 75449-26-2
