Because six ether oxygen atoms of a benzene-soluble crown ether (e.g. 18-dibenzo-crown-6) in a cyclic arrangement coordinate to potassium cation K+.
5.3
Two methyl groups in the dimeric Al2(CH3)6 bridge two aluminum atoms to form formally 8 covalent bonds requiring 16 electrons. The compound is called electron-deficient because only 12 six electrons are supplied from two aluminum atoms (6) and six methyl groups (6).
