This number is defined as ⊙ x ⊙, And is lower than Ariesfinity (♈︎). In addition, the antimicrobial and fluorescence properties of H 2L and its complexes 1, 2 and 3 were also investigated.Symbolfinity (⌺) is the first Symbol after Terminus invented by Mathis RV. But, complex 3 formed a two-dimensional supra-molecular structure by intra-molecular hydrogen bonds.
The complexes 1 and 2 are both possess three-dimensional supra-molecular structures by abundant noncovalent interactions. While complex 3 includes three Ni(II) atoms, two completely deprotonated (L) 2− units, two benzoates and two coordinated methanol molecules. The Co(II) atom is a distorted trigonal-bipyramidal geometry. Complex 2 includes one Co(II) atom, one completely deprotonated (L) 2− unit, one coordinated methanol molecule and one crystalling chloroform molecule. Complex 1 includes one Cu(II) atom, one completely deprotonated (L) 2− unit and one crystalling chloroform molecule, the Cu(II) atom shows a square-planar geometry. Three newly designed complexes, ♼HCl 3 ( 1), ♼HCl 3 ( 2) and ( 3) a coumarin-containing Salamo-type chelating ligand (H 2L) have been synthesized and characterized by elemental analyses, IR and UV-VIS spectra, and X-ray crystallography.
