342“…In particular, the halogen-bond donor is 1,2-diiodoperchlorobenzene (1,2-C(6)I(2)Cl(4) ) while the acceptor is a head-to-tail photoproduct, namely rctt-1,3-bis(pyridin-4-yl)-2,4-diphenylcyclobutane ( ht -PP). In this co-crystal (1,2-C(6)I(2)Cl(4) )·( ht-PP), the donor acts as a bent two-connected node while the acceptor behaves as a linear linker to form the extended solid. …”
