摘要

A dimorphic form of NH(4)Z center dot H2O; where Z(-) is N-deprotonated ortho-benzenedisulfonimide, has been obtained and structurally characterized (previously known form 1A: monoclinic, P2(1)/c, Z' = 1; new polymorph 1B: monoclinic, P2(1), Z' = 1). Both structures are dominated by an abundance of classical hydrogen bonds N+-H/O-H center dot center dot center dot O=S/OH2, whereby the anionic N- function does not act as an acceptor. The major difference between the dimorphs arises from the topology of the hydrogen bond network, which is two-dimensional in 1A, leading to a packing of discrete lamellar layers, but three-dimensional in 1B. Moreover, the latter network is reinforced by a set of weak C-H center dot center dot center dot O/N hydrogen bonds, whereas the layered structure of 1A displays only one independent C-H center dot center dot center dot O bond, providing a link between adjacent layers. The compound [Ph3PNPPh3]Z (2, monoclinic. P2(1)/c, Z' = 1) is the first structurally authenticated example of an ionic Z(-) derivative in which the cation contains neither metal bonding sites nor strong hydrogen bond donors. This structure exhibits columns of anions, surrounded by four parallel columns of cations, giving a square array. The large cations are associated into a three-dimensional framework via weak C-H center dot center dot center dot C(pi) interactions and an offset face-to-face phenyl interaction, while the anions occupy tunnels in this framework and are extensively bonded to the surrounding cations by C-H center dot center dot center dot O/N- hydrogen bonds and C-H center dot center dot center dot C(pi) interactions.
