The bifunctional ligands of isonicotinic acid (Py-4-COOH) and 4-pyrid-4-ylbenzoic acid (Pybz-4-COOH) instead of polypyridines were therefore reacted with (Re(CO) 4 ) 3 (C 3 N 3 S 3 ) (C 3 N 3 S 3 = cyanurate trianion), resulting in the formation of two trinuclear [(Re(CO) 3 ) 3 (C 3 N 3 S 3 )(Py-4-COOH) 3 ] ( 1 ) and [(Re(CO) 3 ) 3 (C 3 N 3 S 3 )(Pybz-4-COOH) 3 ] ( 2 ), respectively. In the meantime, both complexes 1 and 2 are connected by three bifurcated hydrogen bonds between their carboxylic acid moieties Py-4-COOH and Pybz-4-COOH to form the supramolecular trigonal-prismatic and -antiprismatic structures, respectively. It is noted that complex 1 can further react with copper(II) nitrate upon deprotonation to give nonanuclear [(Re(CO) 3 ) 3 (C 3 N 3 S 3 )(Py-4-COO) 3 ] 2 Cu 3 (H 2 O) 9 ( 3 ), where two trinuclear [(Re(CO) 3 ) 3 (C 3 N 3 S 3 )(Py-4-COO) 3 ] moieties are connected by three penta-coordinate copper(II) ions, each coordinating to two carboxylates and three water molecules, to form the trigonal-prismatic structure. Surprisingly, addition of pyrazine (pz) in the synthetic process of complex 3 resulted in serendipitous isolation of a rare example of octadecanuclear {[(Re(CO) 3 ) 3 (C 3 N 3 S 3 )(Py-4-COO) 3 ] 2 Cu 3 (H 2 O) 6 (pz) 2 } 2 ( 4 ), which can be regarded as a dimer of complex 3 , connected by two bridging pz ligands. Interestingly, both complexes 3 and 4 are heteronuclear molecular Re(I)-Cu(II) boxes, constructed by a complex-as-a-ligand strategy. Furthermore, complexes 1 and 2 can exhibit respective low-energy luminescence at ca . 561 and 534 nm at room temperature upon photoexcitation, and complex 3 is found to display antiferromagnetic coupling of −127.68 and −134.70 cm –1 , possibly due to multiple hydrogen bonds inducing significant Cu(II)···Cu(II) coupling. |
