The educt sodium 5-(8-(((carboxymethyl)amino)methyl)-7-hydroxy-4-oxo-4H-chromen-3-yl)-2-hydroxybenzenesulfonate was synthesized via a Mannich reaction. Formaldehyde solution (10 mL, 37%) and sodium 2-hydroxy-5-(7-hydroxy-4-oxo-4H-chromen-3-yl)benzenesulfonate (3.56 g, 0.01 mol) were added to ethanol (200 mL, 95%) and stirred for 0.5 h at 338 K. Then, the saturated solution of glycine (1.12 g, 0.015 mol) was added to the reaction mixture. Then, water was added until a transparent solution was obtained. After 11 h reaction time, the mixture was filtered, and the residue was collected. Then the residue was dried at 383 K. Sodium 5-(8-(((carboxymethyl)amino)methyl)-7-hydroxy-4-oxo-4H-chromen-3-yl)-2-hydroxybenzenesulfonate (2.262 g, 0.005 mol) was obtained. NMR spectra were recorded on a Bruker AV400 NMR instrument. 1H-NMR (400 MHz, DMSO-d6) δ: 10.59 (s, 1H, H4A), 8.34 (s, 1H, H9A), 7.98 (d, J = 8.9 Hz, 1H, H5B), 7.71 (d, J = 2.3 Hz, 1H, H11A), 7.39 (dd, J = 8.4, 2.3 Hz, 1H, H15A), 7.08 (d, J = 8.9 Hz, 1H, H6B), 6.85 (d, J = 8.5 Hz, 1H, H14A), 4.30 (s, 2H, H16A, H16B), 3.39 (s, 2H, H17A, H17B); 13C-NMR (100 MHz, DMSO-d6) δ: 174.62 (C7), 168.87 (C18), 163.16 (C1), 155.87 (C3), 153.25 (C13), 152.73 (C9), 131.48 (C15), 130.64 (C12), 127.74 (C5), 127.20 (C11), 123.02 (C10), 122.25 (C8), 116.29 (C4), 115.85 (C14), 115.12 (C6), 106.64 (C2), 48.87 (C17), 39.73 (C16).

ESI-MS: m/z 420.17 [M–Na]−. The saturated solution of CoCl2⋅H2O (0.238 g, 0.001 mol) was added to the saturated solution of sodium salt described before (0.443 g, 0.001 mol). The mixture was stirred for 30 min at 343 K and a pink solution was obtained. After cooling to room temperature, red block-shaped crystals of the title compound were obtained. IR spectra (potassium bromide pellet) Nicolet 6700. IR (v/cm−1): 3448, 1629, 1529, 1458, 1432, 1414, 1334, 1285, 1210, 1175, 1100, 1028, 910, 826, 741, 629, 517, 487.
Experimental details
Carbon-bound H atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2 Ueq(C). The oxygen-bound and nitrogen-bound H atoms were located on a difference Fourier map and refined freely.
Discussion
In the last decade, much attention has been focused on flavonoids. The Mannich reaction has been considered as an effective method in introducing aminomethyl substituents into the desired flavonoid molecules to improve their biological activities [5], [6], [7], [8], [9], [10], [11]. The goal of our work is to synthesize amino-acid derivatives of daidzein to obtain substances which have a good water solubility. Increasing the solubility of daidzein derivatives expands the capability for studying their biological activity and increases their bioavailability. To extend this research, we used sodium 5-(8-(((carboxymethyl)amino)methyl)-7-hydroxy-4-oxo-4H-chromen-3-yl)-2-hydroxybenzenesulfonate to react with Co2+ ions and got a new complex. The studies on the bioactivity of the title compound are presently ongoing.
The asymmetric unit of the title structure consists of one half of a monomer complex (cf. the figure, the asymmetric unit is labeled) and three uncoordinated water molecules. The Co(II) atom lies on the inversion center and is six-coordinated by four O atoms from four coordinated water molecules and two O atoms from two monodentate coordinating ligands. The Co(II) atom adopts a slightly distorted octahedral geometry. The Co—O bond distances are in the range of 2.066(4) Å and 2.115(3) Å. The chromen moiety (C1/C6/C5/C4/C7/C8/C9/O2/C3/C2) is essentially planar, with a mean deviation of 0.0182 Å. The carboxylate groups adopt trans conformations, with the C18—C17—N1—C16 torsion angles to be −86.54°. The nitrogen atom N1 is protonated. There exist extensive H-bonding interactions between the ligands via the coordinated water molecules and uncoordinated water molecules to form a 3D supramolecular network. It is obvious that the hydrogen bonds play important roles in the self-assembly and enhance stability of the resultant structure.
