Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 33100-27-5, C10H20O5. A document type is Article, introducing its new discovery., Safety of 1,4,7,10,13-Pentaoxacyclopentadecane
The complex was synthesized by the reaction of freshly prepared Na with 15-crown-5 in toluene.The formation of two liquid layers indicative of a liquid clathrate was noted immediately.The pale green, air-sensitive crystals of the complex belong to the monoclinic space group P21/c with a 7.880(2), b 19.157(8), c 13.549(4) Angstroem, beta 101.78(2) deg, and Dc 1.45 g cm-3 for Z = 4 formula units.The structure in the solid state is that of a dimer which resides on a crystallographic center of inversion.The – units are bridged together by sodium cations.The latter are coordinated to one equatorial carbonyl oxygen atom, one axial carbonyl oxygen atom, and the five oxygen atoms of the crown ether.The two Na…O(carbonyl) contacts are 2.409 and 2.555 Angstroem, and the sodium ion lies 0.88 Angstroem out of the plane of the crown ether oxygen atoms.
