N2  - Five new multidentate ligands have been prepared containing N,N-bidentate pyrazolyl&#8211;pyridine units linked to a central aromatic spacer unit. The ligands 3,3&#8242;-bis(3-{pyridin-2-yl}-pyrazol-1-yl-methyl)-p-terphenyl (1), 4,4&#8242;-bis(3-{pyridin-2-yl}-pyrazol-1-yl)biphenyl (2), and 1,8-bis(3-{pyridin-2-yl}-pyrazol-1-yl-methyl)naphthalene (3) have two bidentate arms and are therefore potentially tetradentate; 2,6-bis(3-{pyridin-2-yl}-pyrazol-1-yl-methyl)pyridine (4) has two bidentate arms with an additional nitrogen-donor in the aromatic spacer unit (a pyridyl group) and is therefore potentially pentadentate; and 1,3,5-trimethyl-2,4,6-tris(3-{pyridin-2-yl}-pyrazol-1-yl-methyl)benzene (5) has three bidentate arms and is therefore potentially hexadentate. The X-ray crystal structures of all of these ligands have been determined.
