摘要

Low-temperature X-ray structures are reported for (4-I-C6H4SO2)(2)NAg (1, triclinic, P (1) over bar, Z' = 1) and (4-F-C6H4SO2)(2-)NH center dot H2O (2, orthorhombic, Pna2(1), Z'= 2). Whereas metal di-(arenesulfonyl)amides usually display folded anions (C-S center dot center dot center dot S' -C' synperiplanar) and crystallize in lamellar layers, compound 1 has an extended anion (C-S center dot center dot center dot S'-C' antiperiplanar) and forms non-lamellar striated layers in which the ions are connected by Ag-N/ Ag-O bonds in one dimension and by Ag-I-C interactions, C-I center dot center dot center dot O halogen bonds and weak pi/pi ring interactions in the other dimension. The silver ion adopts a trigonal-bipyramidal pentacoordination comprising two long axial Ag-O bonds (259 and 261 pm), one short Ag-N bond (228 pm) and two structure-determining Ag-I bonds (289 and 294 pm, Ag-I-C 107 and 109 degrees). An analysis of Ag center dot center dot center dot I-C contacts < 340 pm extracted from the Cambridge Structural Database (25 structures, 63 contacts) reveals that the Ag-I-C angles lie between 90 and 110 degrees for contacts < 300 pm, whereas for longer interactions, the directionality rapidly becomes weaker; this result is in keeping with the electrophileucleophile model for interactions involving halogen atoms bonded to carbon. In the structure of compound 2, a dimer of two independent water molecules is repeated via glide planes to give a chain ill which water I acts as a difunctional hydrogen bond donor and water 2 as a difunctional acceptor. The extended disulfonylamine molecules are connected to water 1 by N-H center dot center dot center dot O(w), to water 2 by O(w)-H center dot center dot center dot O=S bonds. The resulting supramolecular polymer is a square column that is reinforced by C-H... O=S hydrogen bonds and pi/pi interactions and bears four one-dimensional sets of fluorine atoms at the vertices. Dense packing of these columns causes all the fluorine atoms to segregate into parallel tunnels and to form short C-H center dot center dot center dot F-C intercolumnar contacts strongly suggestive of weak hydrogen bonding (H center dot center dot center dot F 240-250 pm, C center dot center dot center dot F 328-346 pm, C-H center dot center dot center dot F 137-148 degrees).

O = S氢键和pi / pi相互作用增强的方柱,并且在顶点处带有四个一维的氟原子集。这些柱子的密集堆积导致所有氟原子分离成平行的隧道,并形成短的CH中心点中心点中心点FC柱间接触,强烈暗示氢键弱(H中心点中心点中心点F 240-250 pm,C中心点中心点中心点F 328-346 pm,CH中心点中心点中心点F 137-148度)。
