The molecular and supramolecular structures of three new lead(II) complexes with the pincer-type ligand 4′-chloro-2,2′:6′,2″-terpyridine (TpyCl)
چکیده انگلیسی

Three new 1:1 complexes of lead(II) with the pincer-type ligand 4′-chloro-2,2′:6′,2″-terpyridine (TpyCl), [Pb(TpyCl)(NO3)2]n(1), [Pb(TpyCl)(ClO4)2]n(2) and [Pb(TpyCl)Br2]2(3), have been synthesized and characterized by X-ray crystal structure determination as well as spectroscopy and thermal analysis. 1 and 2 are coordination polymers in which the coordination polyhedra are linked via nitrate and perchlorate ligands, respectively, to chains. 3 exhibits a dimeric molecular structure with Pb(μ-Br)2Pb type bridging. In all three compounds the chains and the oligomers are connected to networks via supramolecular interactions which include O···O, C–H···O, C–H···Cl and C–H···Br hydrogen bonding and π–π stacking as well.
