Comparison of the supramolecular organization in their native crystals and respective cocrystals with the iconic halogen bond donor, 1,4-diiodotetrafluorobenzene (p-DITFB), demonstrate three different patterns: 1) conservation of the chain structures for FcTeTeI(2) Fc, 2) transformation of single Se center dot center dot center dot Se intermolecular interaction to double for FcSe(3), and 3) for Fc(2)Te(2), in the absence of specific and directed intermolecular interactions, the cocrystal packing of Fc(2)Te(2) is governed only by p-DITFB HaBs directionality. This allows a rough glimpse of ferrocenic polychalcogenides structural landscape and shows the directions and methods for its further detailization. (C) 2021 Elsevier B.V. All rights reserved. 收起
