β¦ Synopsis
l3slinctive pallems of C.. C, CI._.CI and C...CI non-bonded short contacLs are oblained for 4 A short axis fi-structures and for nor&s~~ctures in a senes of polychlor~aromatics, phenols and anilines. The direclions of the shortest Cl _ _ _ Cl and C.--C contacts provide an insight mto the role or the chloro-subsliluenl as a skcring group in the crystal engineering of Although the hterature has been controversial with regard to the ongin and nature of Cl...Cl lnteractlons in orgamc molecular solids [l-3], there is little doubt that short mtermolecular Cl...Cl contacts, which may be aslow as 3.21 A [3]', are found widely in the structures of chloro-compounds, especrally polychloro-

Whenever hydrogen bonding is involved in molecular recognition, the possibility of a proton transfer from the donor to the acceptor arises. In most cases the pK a of the donor is far enough above the pK a of the conjugate acid of the acceptor for it to be clear that no proton transfer will occur. Ho
