两个新的希夫碱,N - ((pyridin-2-yl) formylidene)苄胺(pfba)和N - ((pyridin-2-yl)苯亚甲基)苄胺(pbba)准备。两个系列的hexacoordinated锌(II) pseudohalide复合物的类型(锌(L) 2 (X) 2) (L: pfba;X = N3 - (1);X = nc - (1 b);X =甲- (1 c)和L: pbba;X = N3 -, (2);X = nc - (2 b);X =甲- (2 c)已经开发使用这两种希夫碱。元素、光谱和其他理化结果描述复合物。结构(锌(pbba) 2 (N3) 2](2)解决了x射线衍射测量。 (2a) crystallizes in the orthorhombic space group P21/c with a=16.6671(2) Å, b=44.4722(8) Å, c=8.9687(1) Å, α=90.00°, β=90.00°, Z=8. Structural analyses reveal that each zinc(II) in (2a), has an distorted octahedral geometry with ZnN6 chromophore coordinated through four N atoms of two bidentate pbba units and two N atoms of terminal azide in1 mutual cis orientation. The mononuclear units are engaged intermolecular C-H…N hydrogen bonding resulting 1D molecular chain. All the complexes display intraligand[1](π- π*) fluorescence and intraligand[3](π-π*) phosphorescence in glassy solutions (MeOH at 77 K).
