基于2-丙基-4,5-咪唑二甲酸配体合成了2个新型锶和钡配合物,分别为[Sr(H2pimda)2(H2O)2]n(1)和{[Ba(H2pimda)2(H2O)3]H2O}n(2),(H3pimda=2-丙基-4,5-咪唑二甲酸),用元素分析、红外光谱、热重分析对产物进行表征,用单晶X-射线衍射方法测定了配合物1和2的晶体结构。配合物1属于单斜晶系C2/c空间群,晶胞参数:a=1.30718(12)nm,b=1.31913(12)nm,c=1.16824(11)nm,β=98.477 0(10)°。配合物2属于三斜晶系P1空间群,晶胞参数:a=1.0316 0(10)nm,b=1.054 60(10)nm,c=1.098 11(11)nm,α=75.878 0(10)°,β=78.512 0(10)°,γ=84.399(2)°。并且研究了配合物1的荧光性质。
Two novel strontium and barium complexes were synthesized based on 2-propyl-4,5-imidazolecarboxylate ligands, which are [Sr (H2pimda) 2 (H2O) 2] n (1) and {[Ba (H2pimda) 2 (H2O) 3] H2O} n (2) (H3pimda = 2-propyl-4,5-imidazolecarboxylate). The product was characterized by elemental analysis, The crystal structures of complexes 1 and 2 were determined by the X-ray diffraction method. Complex 1 belongs to the monoclinic C2 / c space group with unit cell parameters of a = 1.30718 (12) nm, b = 1.31913 (12) nm, c = 1.16824 (11) nm and β = 98.477 0 . The complex 2 belongs to the triclinic P1 space group with the unit cell parameters of a = 1.0316 0 (10) nm, b = 1.054 60 (10) nm, c = 1.098 11 °, β = 78.512 0 (10) °, γ = 84.399 (2) °. The fluorescence properties of complex 1 were also studied.
