Synthesis, crystal structure and luminescent properties of manganese 3,3'-dicarboxy-2,2'-bipyridine induced by hydrolysis of 1,10-phenanthroline-5,6-dione
The manganese coordination compound [Mn(dcb)(H2O)4]n has been obtained by hydrothermal synthesis by using Mn(CH3COO)2 · 2H2O and 1,10-phenanthroline-5,6-dione, where dcb = 3,3'-dicarboxy-2,2'-bipyridine. The results of X-ray single-crystal diffraction reveal that the title complex forms a chain-like 1D structure. The complex [Mn(dcb)(H2O)4]n crystallizes in the orthorhombic system, space group P2(1)2(1)2, with lattice parameters a = 13.896(3) Å, b = 6.3507(12) Å, c = 8.3745(15) Å, V = 739.1(2) Å3, Dc = 1.659 Mg m-3, Z = 2, F(000) = 378, GOF = 0.999, R1 = 0.0283, wR2 = 0.0719. The photophysical properties have been investigated with fluorescence excitation and emission spectra.
