3-(pyridin-2-yl)-1,2,4-triazole was synthesized through two steps from the raw material 2-cyanopridine,and a series of derivatives(3a～3d)which were reported in this paper were synthesized by the reaction of 3-(pyridin-2-yl)-1,2,4-triazole with(o-,m-,p-)2-chloro-methyl pyridine.Their structures were characterized by elementary analyses,IR,1H NMR and 13C NMR.
A dinuclear manganese(Ⅱ) complex, [Mn2(L1)2(phen)4]·(ClO4)2 (1), has been synthesized and structurally characterized (HL1=2,6-dichlorobenzoic acid, phen=1,10-phenanthroline). It crystallizes in triclinic system, space group P1 with a=1.112 3(4) nm, b=1.378 2(4) nm, c=2.085 7(3) nm, α=93.768(2)°, β=90.606(10)°, γ=95.606(3)°, V=3.174 8(15) nm3, Z=2, C62H38Cl6Mn2N8O12, Mr=1 409.58, Dc=1.475 g·cm-3, μ=0.718 mm-1, F(000)=1 428, R=0.064 3, wR=0.138 3. In the crystal the manganese atom is six-coordinated by two oxygen atoms from two different 2,6-dichlorobenzolate molecules and four nitrogen atoms from two 1,10-phenanthroline molecules, completing an octahedral geometry.
