Hybrid Organic-Inorganic Copper and Cobalt Complexes for Antimicrobial Potential Applications.

Background/aims: The naturally occurring phenolic chemical curcumin (CUR), which was derived from the Curcuma longa plant, has a variety of biological actions, including anti-inflammatory, antimicrobial, antioxidant, and anticancer activities. Curcumin is known for its restricted bioavailability due to its hydrophobicity, poor intestinal absorption, and quick metabolism. To boost the biological effects of these bioactive molecules, it is necessary to raise both their bioavailability and their solubility in water.

Bis(propane-1,3-diaminium) hexa-fluoridoferrate(III) fluoride trihydrate.

The asymmetric unit of the title iron hybrid fluoride, (C(3)H(12)N(2))(2)[FeF(6)]F·3H(2)O, contains two propane-1,3-diamin-ium [(H(2)dap)(2+)] cations, an octa-hedral [FeF(6)](3-) anion, an isolated F(-) anion and three water mol-ecules of solvation. Each [FeF(6)](3-) anion is surrounded by four separate hydrogen-bonded water mol-ecules in the equatorial sites and by five separate aminium cation donor groups. The axial F atoms are only involved in N-H⋯F hydrogen bonds, resulting in a three-dimensional structure.
