Three newly designed containing-PMBP N2O2-donors complexes, [Co(L-1)(CH3OH)(2)] (1), [{Zn(L-2)(CH3OH)(H2O)}(3)] (2) and [Cu-4(L-2)(4)].2CHCl(3) (3), have been synthesized and structurally characterized using elemental analyses, infrared and UV-visible spectroscopies and single-crystal X-ray diffraction. X-ray crystal structure determinations revealed that 1 consists of one Co(II) atom, one completely deprotonated (L-1)(2-) unit and two coordinated methanol molecules. Complex 2 consists of three Zn(II) atoms, three completely deprotonated (L-2)(2-) units, three coordinated methanol molecules and three coordinated water molecules. However, 3 includes four Cu(II) atoms, four completely deprotonated (L-2)(2-) units and two crystallization chloroform molecules. The Co(II) and Zn(II) atoms in the structures of 1 and 2 adopt slightly distorted octahedral geometries. While, Cu(II) atoms in 3 can be best described as adopting slightly distorted square planar geometries. Complex 2 is a novel structure, and the ratio of H2L2 to Zn(II) atom is 3:3. In addition, two-, three- and three-dimensional supramolecular structures were constructed for 1, 2 and 3. Most importantly, Hirshfeld surface analysis of 1, 2 and 3 was conducted and fluorescence properties were investigated.
