General Description

(4-butoxy-2-hydroxyphenyl)(phenyl)methanone is a chemical compound with the molecular formula C20H22O3. It is also known as benzophenone-3 and is commonly used in sunscreen and cosmetic products as a UV filter. (4-butoxy-2-hydroxyphenyl)(phenyl)methanone is able to absorb and dissipate UV radiation, protecting the skin and hair from damage caused by sun exposure. It is a white, crystalline solid that is insoluble in water but soluble in organic solvents. Its use in personal care products has raised some concerns about its potential impact on human health and the environment, leading to further research into its safety and efficacy.

Synthesis, characterization, and structural determination of copper(II) complexes with alkyl derivatives of hydroxybenzophenones

Four mononuclear copper(II) complexes, [Cu(LFQM-115)2] (1), [Cu(LFQM-116)2] (2), [Cu(LFQM-117)2] (3) and [Cu(octyloxy)2] (4) [LFQM-115?=?2-hydroxy-4-O-methylbenzophenone (C14H11O3), LFQM-116?=?2-hydroxy-4-O-butylbenzophenone (C17H18O3), LFQM-117?=?2-hydroxy-4-O-(33-dimethylallyl)benzophenone (C18H18O3) and octyloxy?=?2-hydroxy-4-O-octylbenzophenone (C21H25O3)], have been prepared and investigated by infrared spectroscopy, thermal analysis, and powder and single crystal X-ray diffraction. Even though the synthesis and infrared analysis of 1, 2, and 4 have been reported previously, their crystal structures were elucidated for the first time here. In addition, the crystal structures of LFQM-116 and LFQM-117 were also determined by single crystal X-ray diffraction. The pseudo-translational symmetry found in LFQM-116 and the isomorphism between LFQM-115 and LFQM-117 are discussed. The complexes were prepared from a reaction of copper(II) nitrate trihydrate and the respective ligand in a (1:2) molar ratio in methanol (for 1 and 2) or THF (for 3 and 4) with addition of NaOH. Furthermore, crystallographic studies show that each copper(II) exhibits a square planar geometry, coordinated by four oxygens of two ligands. The nature and crystal packing of the intermolecular interactions are discussed. Compounds 2 and 3 are isomorphic crystals and all structures have the same supramolecular synthon.
