Cadmium(II) complexes of 4′-tolyl-2,2′:6′,2′′-terpyridine: synthesis, structures, and antibacterial activities

A straightforward synthetic method has been developed to prepare cadmium(II) complexes of 4′-tolyl-2,2′:6′,2″-terpyridine (ttpy) in good yields. These complexes are formulated as {[Cd(ttpy)(NO 3 ) 2 ][Cd 2 (ttpy) 2 (NO 3 ) 4 ]} (1), [Cd 2 (ttpy) 2 (N 3 ) 4 ]0.5CH 3 OH · 0.125H 2 O (2), and {[Cd(ttpy...

Summary:A straightforward synthetic method has been developed to prepare cadmium(II) complexes of 4′-tolyl-2,2′:6′,2″-terpyridine (ttpy) in good yields. These complexes are formulated as {[Cd(ttpy)(NO 3 ) 2 ][Cd 2 (ttpy) 2 (NO 3 ) 4 ]} (1), [Cd 2 (ttpy) 2 (N 3 ) 4 ]0.5CH 3 OH · 0.125H 2 O (2), and {[Cd(ttpy)(SCN)(CH 3 COO)][Cd(ttpy)(SCN) 2 ] 2 } (3). Intermolecular, intramolecular, hydrogen bonding and π-π stacking interactions were observed in the complexes, and are responsible for the arrangement of complexes in the crystal packing and play essential roles in forming different frameworks of 1-3. The antibacterial activities of the synthesized complexes were tested against three gram positive bacteria and three gram negative bacteria.
