Abstract	Abstract As an exercise in crystal engineering, preparations and low-temperature X-ray structures are reported for three ionic solids of general formula BH+(MeSO2)2N−, where BH+ is 2,4,6- triaminopyrimidinium (compound 1, triclinic, space group P1, Z = 2), 2,6-diaminopyridinium (2, monoclinic, C2/c, Z = 8), or 2,4-diaminopyrimidin-6(1H)-on-3-ium (3, monoclinic, P21/c, Z = 4). As a common feature, the onium cations in question exhibit a trifunctional hydrogen-bond donor sequence H-N-C-N(H)-C-N-H that is complementary to a W-shaped O-S-N-S-O fragment of the anion. Consequently, each structure displays a [DDD:AAA] three-point hydrogen-bond pattern formed by two lateral N-H···O bonds and a central N-H···N interaction. This grouping is integrated as a robust supramolecular synthon into two-dimensional (1, 2) or three-dimensional (3) hydrogen-bond networks, in which all good donors and all good acceptors are involved (excepting one S=O group in 2). In structure 1, the approximately planar cation-anion layers are perfect mosaics composed of 6-membered pyrimidine heterocycles and seven crystallographically independent types of 8-, 10-, 12- or 24-membered rings based upon hydrogen bonding. In contrast, the corresponding layers in structure 2 are marred by large 40-membered voids; in order to achieve dense packing, the imperfect layers adopt a strongly corrugated shape and interpenetrate to form twofold interwoven and nearly planar double-layers. Each structure features close C-H···O contacts consistent with weak hydrogen bonding; in the layer structures 1 and 2, some of these interactions serve as links between adjacent or interwoven layers.
