Abstract

Solvothermal reaction of manganese(II) salt with monosodium 2-sulfoterephthalate (2-NaH2stp) and two multi-pyridine N-containing auxiliary ligands results in the formation of two new complexes formulated with [Mn2(Hstp) 2 (bpp) 2 (H2O)4] (1) and [Mn3 (stp) 2 (tpy) 3 (H2O)](H2O) 5 (2) (bpp = benz-2,3-pyrimidine-[2,3-f]-1,10-phenanthroline, tpy = 2,2′:6′,2′′-terpyridine). X-ray diffraction structural analyses of two complexes reveal their structural diversity (0D and 1D) due to the difference of auxiliary ligands. 1 is a discrete structure, in which the Mn(II) ion is hexa-coordinated with one stp, one bpp ligand and two water molecules. Complex 2 is a one-dimensional (1D) chain-like structure with three crystallographically independent Mn(II) ions. The photoluminescent properties could be assigned to the π-π∗ transition of 2-sulfoterephthalate ligands.
