Using visible light to activate antiviral and antimicrobial properties of TiO nanoparticles in paints and coatings: focus on new developments for frequent-touch surfaces in hospitals.

Unlabelled: The COVID-19 pandemic refocused scientists the world over to produce technologies that will be able to prevent the spread of such diseases in the future. One area that deservedly receives much attention is the disinfection of health facilities like hospitals, public areas like bathrooms and train stations, and cleaning areas in the food industry. Microorganisms and viruses can attach to and survive on surfaces for a long time in most cases, increasing the risk for infection.

Crystal structures of chlorido-[dihy-droxybis-(1-imino-eth-oxy)]arsanido-κ ,,']platinum(II) and of a polymorph of chlorido-[dihy-droxybis-(1-imino-prop-oxy)arsanido-κ ,,']platinum(II).

Each central platinum(II) atom in the crystal structures of chlorido-[dihy-droxybis-(1-imino-eth-oxy)arsanido-κ ,,']platinum(II), [Pt(CHAsNO)Cl] (), and of chlorido-[dihy-droxybis-(1-imino-prop-oxy)arsanido-κ ,,']platinum(II), [Pt(CHAsNO)Cl] (), is coordinated by two nitro-gen donor atoms, a chlorido ligand and to arsenic, which, in turn, is coordinated by two oxygen donor ligands, two hydroxyl ligands and the platinum(II) atom. The square-planar and trigonal-bipyramidal coordination environments around platinum and arsenic, respectively, are significantly distorted with the largest outliers being 173.90 (13) and 106.
