Syntheses, Crystal Structures and Fluorescence Properties of Two Cobalt(II) and Manganese(II) Coordination Polymers

Two new metal complexes, [Mn-3(Hidc)(3)(DMI)(2)](n) (1) (H(3)idc=4,5-imidazoledicarboxylic acid, DMI=1,3-dimethyl-2-imidazolidinone) arid [Co(tbip)(DMPU)](n), (2) (H(2)tbip=5-tert-butylisophthalic acid, DMPU=N,N-dimethylpropyleneurea), have been synthesized by urothermal method. The single crystal X-ray diffraction analysis shows that complex 1 exhibits a three-dimensional structure with square-shaped pores constructed by H(3)ide and Mn(II), and DMI molecules are filled in the pores. Complex 2 is a two-dimensional network structure constructed by H(2)tbip and Co(II) using DMPU as a template, and DMPU molecules are filled in the grids of network by coordinating with Co (II). Solid fluorescence measurement reveals that complex 1 possesses blue fluorescence property with a strong emission at 462 nm. CCDC: 1943672, 1; 1943671, 2.
