Hydrothermal Synthesis and Crystal Structure of a Complex with Pyrogallic Acid and N-donor Ligand: 2-(4-methoxyphenyl)-1H-imidazo[4,5-f][1,10] Phenanthroline
摘要:
The complex [Ni(MOPIP)(3)(C6H5O3)](n)center dot nH(2)O 1 (C6H5O3 = pyrogallic acid, MOPIP = 2-(4-methoxyphenyl)-1H-imidazo[4,5-f][1,10] phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG, and single-crystal X-ray diffraction. Complex 1 crystallizes in the monoclinic system, space group P 21/c, with a = 17.249 (3), b = 15.014 (3), c = 21.437 (4) angstrom, = 92.14 (3), V = 5547.7 (19) angstrom(3), and Z = 4 [at 293 (2) K]. In the crystal structure, the nickel atom is six coordinated with six nitrogen atoms from MOPIP ligand, showing a slightly distorted octahedral geometry. Furthermore, it exhibits a zero-dimensional (0D) structure with Ni-MOPIP as building units. The complex 1 extends 3D supramolecular structure through the hydrogen bonds and the - stacking interactions enhance the stability of the complex.
