摘要:
New coordination compounds of zinc with 3-(pyridine-2-yl)-5-(2-salicylideneiminophenyl)-1H-1,2,4-triazole (H(2)L(1)) and 3-(pyridine-4-yl)-5-(2-salicylideneiminophenyl)-1H-1,2,4-triazole (H(2)L(2)) are obtained. According to X-ray diffraction data, binuclear zinc complexes with L(1), namely, [Zn(2)L (2) (1) ]. 0.5EtOH and [Zn(2)L (2) (1) ] center dot 2C(4)H(8)O(2) center dot 2H(2)O obtained in different solvents, are structurally related molecular complexes. The product of the reaction with H(2)L(2) is the {[ZnL(2)(Py)] center dot CHCl(3)} (n) coordination polymer. The 1,2,4-triazoles under study and the complexes on their basis luminesce in solutions with emission maxima ranging from 412 to 503 nm. These coordination compounds in the solid state emit in the green range of the spectrum (lambda(max) = 496 and 485 nm).
