Source of materials

Synthesis of the ligand: All reagents and starting materials were obtained from commercial suppliers and used as received. The ligand was synthesized according to an analogous method reported in the literature [3]. To an ethanolic solution (5 mL) of 2-hydroxy-4-methoxybenzaldehyde (152.2 mg, 1 mmol) was added an ethanolic solution (5 mL) of 3-amino-4-hydroxy-2H-chromen-2-one (177.2 mg, 1 mmol). The solution was stirred under reflux conditions at 434 K for 6 h. After cooling to room temperature, the precipitate was filtered and washed with ethanol and n-hexane. The product was dried under vacuum and a yellow solid was obtained (yield 71.8%, m.p. 460–461 K). Elemental analysis – Anal. calcd. for C17H13NO5 (%): C, 65.59; H, 4.21; N, 4.50. Found (%): C, 66.47; H, 4.13; N, 4.85.

Synthesis of the chromium(III) complex: A methanolic solution (5 mL) of chromium acetate dihydrate (3.00 mg, 0.012 mmol) was added dropwise to a mixed solution composed of triethylamine (0.5 mL) and the dichloromethane solution (3.5 mL) of 4-hydroxy-3-[(2-hydroxy-4-methoxy-benzylidene)-amino]-benzopyran-2-one (3.90 mg, 0.012 mmol) at room temperature. The solution turned to dark yellow immediately and the filtrate was allowed to stand at room temperature for about three weeks. Dark-brown block crystals were obtained. Elemental analysis – Anal. calcd. for C38H36Cr2N2O14 (%): C, 53.78; H, 4.28; N, 3.30. Found (%): C, 54.47; H, 4.13; N, 3.65.

Experimental details

Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.

Comment

It is generally known that coumarine and its derivatives have been found to exhibit antibiotic, antibacterial, and plant regulating activities. A Schiff base is a compound with a carbon-nitrogen double bond (−C=N−), which have been studied extensively as a class of ligands [4, 5] . And they can form many types of stable metal complexes [6], [7], [8], [9], which are considered more and more important because of their topology and are widely used in biochemistry [10, 11] . Some of them have magnetic properties [12, 13] , photophysical properties [14, 15] , and are used in the field of molecular recognition [16], [17], [18]. Herein, a new chromium(III) complex with the coumarin-Schiff base ligand (4-hydroxy-3-((2-hydroxy-4-methoxybenzylidene)amino)-2H-chromen-2-one) is reported.

The crystal structure is only built up by C38H36Cr2N2O14 complexes. The title complex is a binuclear complex, and crystallizes in the triclinic space group P1̄. The asymmetric unit consists of one Cr(III) ion, one organic tridentate ligand one deprotonated μ2-methoxy anion (μ2-OMe) and one coordinated methanol molecule (cf. the figure). The Cr(III) center is hexa-coordinated, leading to a slightly distorted octahedral geometry by N, O, O atoms of a deprotoned organic chelating ligand, two O atoms from deprotonated μ2-OMe and one O atoms of a methanol molecule.

In the crystal structure, there are weak non-classical intermolecular hydrogen bonds, which link the complex into an infinite 2D-layer supramolecular structure along the bc plane. This linkage is further stabilized by the intermolecular C—H⋯π interactions to form a 3D supramolecular network structure. The geometric parameters – especially those of the 3-((4-methoxy-2-oxidobenzylidene)amino)-2-oxo-2H-chromen-4-olato ligand are in expected ranges [19, 20] .
