Anion-mediated self-assembly: Five Cd(ІІ) coordination aggregates with a mercaptotetrazole ligand

Four transition metal complexes constructed with mixed mercaptotetrazole and 4,4′-bipyridine ligands

“…It is well known that Cd(II) complexes can exhibit interesting luminescence properties [8,24]. The solid-state luminescence of the free Na 2 mtms ligand and complexes 1 and 2 was investigated at room temperature and is shown in Fig.…”

“…Several previous studies have shown that geometries and sizes of ligands, the coordinating ability of anions, and the nature of metals are all important in determining the structures of such complexes [3][4][5][6][7][8]. N-heterocycles with sulfhydryl ligands are capable of -N(H)-C(=S) $ -N=C(-SH) tautomerization.…”

“…N-heterocycles with sulfhydryl ligands are capable of -N(H)-C(=S) $ -N=C(-SH) tautomerization. Heterocyclic nitrogen can participate in coordination, while the sulfhydryl moiety can be used as a bridging group [8][9][10][11][12][13][14]. The soft sulfhydryl group has good coordination ability, because it has empty 3d orbital that can accept electrons from the metal [8,[14][15][16].…”

The soft sulfhydryl group has good coordination ability, because it has empty 3d orbital that can accept electrons from the metal [8,[14][15][16]. Recently, research into nitrogen heterocycles with sulfhydryl ligands has mainly concentrated on sulfhydryl imidazole, sulfhydryl-(1,2,4)-triazole, and sulfhydryl tetrazole [8,14,[17][18][19].…”
