14187-32-7. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6.
Crown ether complexation of PrCl+2 : Synthesis and structural characterisation of [PrCl2(dibenzo-18-crown-6)(H2o)][SbCl6] ¡¤ 0.5MeOH ¡¤ 0.5MeCN
Treatment of PrCl3(MeCN)3.5 with antimony(V) chloride in the presence of dibenzo-18-crown-6 provided yellow needle crystals of [PrCl2(dibenzo-18-crown-6)(H2O)] [SbCl6] ¡¤ 0.5MeOH ¡¤ 0.5MeCN following recrystallisation of the initial reaction product from boiling CH3OH/CH3CN (50 : 50). The ionic formulation was verified by X-ray crystallography. The cations have crystallographic m symmetry and the metal atoms are nine coordinate involving binding to all six crown oxygen atoms Pr – Ocrown 2.651(11)2.668(10) A, mean 2.658(10) A, two chlorine atoms 2.740(4), 2.749(4) A and a water molecule Pr – OH2O 2.487(10) A.
