WebHe potassium bromide (KBr) is a haloide salt produced by a highly electropositive element, such as potassium (K), and highly electronegative, such as bromine (Br). The physical aspect is a white crystalline solid and is hygroscopic; that is, it absorbs water from the medium. ... Structure (solid state) Crystal structure: sodium chloride ... WebA novel series of biscoumarin (1–4) and dihydropyran (5–13) derivatives were synthesized via a one-pot multicomponent condensation reaction and evaluated for antibacterial and antitumor activity in vitro. The X-ray crystal structure analysis of four representative compounds, 3, 7, 9 and 11, confirmed the structures of these compounds. Compounds …
