| Abstract: Two strontium and barium complexes based on 2-propyl-1H-imidazole-4,5-dicarboxylic acid, namely [Sr(H2pimda)2(H2O)2]n (1), {[Ba(H2pimda)2(H2O)3]H2O}n (2), (H3pimda=2-propyl-1H-imidazole-4,5-dicarboxylic acid) have been synthesized and characterized by elemental analysis, infrared spectroscopy, thermogravimetric analysis (TGA) and single-crystal X-ray diffraction. Complex 1 is of monoclinic space group C2/c with the cell dimensions: a=1.307 18(12) nm, b=1.319 13(12) nm, c=1.168 24(11) nm, β=98.477 0(10)°, Complex 2 is of triclinic space group P1 with the cell dimensions: a=1.031 60(10) nm, b=1.054 60(10) nm, c=1.098 11(11) nm, α=75.8780(10)°, β=78.512 0(10)°, γ=84.399(2)°. Furthermore, the luminescent property of complex 1 has also been investigated. CCDC: 800152, 1; 806347, 2. |
