摘要	Six temperature-dependent Zn(II) complexes 1-6 based on the simple Schiff base L-1 from condensation of equivalent 2-pyridine formaldehyde (2-Pfd) and 2-pyridylethylamine (2-Pea) were systematically studied for the first time. These six complexes are: two complexes of (ZnLX2)-X-2 (1 and 2) involving in situ formed N-rich heterocyclic ligand L-2 at 80 degrees C; two complexes of [Zn-2(cis-L-3) X-4.S] (S = H2O for 3, S = 0 for 5) involving in situ formed azaheterocyclic ligand cis-L-3 at 100 degrees C; and the rest two ones of [[Zn-2(trans-L-3) X-4] (4 and 6) involving in situ formed azaheterocyclic ligand trans-L-3 at 120 degrees C (where X = Cl (1, 3, 4) and N-3 (2, 5, 6), L-1 = N-(2pyridylmethyl)-pyridine-2-carbaldimine, L-2 = 1-pyridineimidazo-[1,5-a] pyridine, L3 = 1-(1,2-di(pyridin-2-yl)-2(3-(pyridin-2-yl) H-imidazo-[1,5-a]-pyridin-1-yl)-ethyl)-3-(pyridin-2-yl) H-imidazo-[1,5-a] pyridine). Interestingly, three Cl-based complexes 1, 3, 4 under appropriate conditions can be irreversibly translated into the corresponding N3-based 2, 5, 6, respectively. The possible formation/conversion mechanism shows that the aH activation in -CH=N-CH2-moiety of L1 coordinated to Zn2+ ion should be the original driving force for the intermolecular C-C/C-N coupling and ring formation reactions, meanwhile reaction temperature also plays a very important role during the formation/conversion of 1-6. Moreover, the results indicate that complexes 1-6 have good fluorescence properties as potential fluorescent materials.
