Supramolecular structural motifs in compounds of acetoguanamine and various carboxylic acids: N-H?O heterosynthons and N-H?N homosynthons

Acetoguanamine is an advantageous molecular precursor for a freshly identified N-H?O/N-H?N synthon, which is adequate for the design of novel multi-dimensional structures. Six compounds of acetoguanamine with various carboxylic acids pyridine-2,3-dicarboxylic acid 1, phthalic acid 2, 3,4,5-trimethoxybenzoic acid 3, 5-chloro-2-hydroxy-benzoic acid 4, 1,2,3,4-cyclopentane-tetracarboxylic acid 5, terephthalic acid 6, were synthesized and investigated. The N-H?O/N and C-H?O interactions bring about the formation of supramolecular aggregation patterns with rich structures. Compounds 1–4 are featured as 2D supramolecular structure while compounds 5 and 6 are novel 3D supramolecular aggregation patterns. Synthon strategy gives a major push to the construction of these six supermolecular compounds. The hetersynthon I R2 2(8) constructed by N-H?O/N+-H···O– H-bond interaction between the deprotonated carboxyle and the protonated triazine is observed in all structures except 3. The homosynthon III R2 2(8) constructed by N-H?N H-bond interaction between acetoguanamine is observed in all structures except 2. What is worth mentioning, compounds 1 and 3–6 feature the 1D chain structures constructed by various synthons and in 3, 4 and 6 the chains are positioned into infinite 2D sheets. What's more, solvent molecule play a vital role in 4 and 6. Besides, the thermal stabilities of complexes 1–6 have been investigated.

Charge-assisted hydrogen-bonded supra-molecular networks in acetoguanaminium hydrogen phthalate, acetoguanaminium hydrogen maleate and acetoguanaminium 3-hydroxy-picolinate monohydrate

In 2,4-diamino-6-methyl-1,3,5-triazin-1-ium (acetoguan-amin-ium) hydrogen phthalate, C4H8N5+·C 8H54 -, (I), aceto-guan-aminium hydrogen maleate, C4H8N5 +· C4H3O4 -, (II), and acetoguanaminium 3-hydroxy-picolinate monohydrate, C4H8N5 +·C6H4NO3 -·H2O, (III), the acetoguanaminium cations inter-act with the carboxyl-ate groups of the corresponding anions via a pair of nearly parallel N - H...O hydrogen bonds, forming R2 2(8) ring motifs. In (II) and (III), N - H...N base-pairing is observed, while there is none in (I). In (II), a series of fused R 32(8), R22(8) and R3 2(8) hydrogen-bonded rings plus fused R22(8), R62(12) and R22(8) ring motifs occur alternately, aggregating into a supra-molecular ladder-like arrangement. In (III), R22(8) motifs occur on either side of a further ring formed by pairs of N - H...O hydrogen bonds, forming an array of three fused hydrogen-bonded rings. In (I) and (II), the anions form a typical intra-molecular O - H...O hydrogen bond with graph set S(7), whereas in (III) an intra-molecular hydrogen bond with graph set S(6) is formed.

Syntheses and characterizations of three acid-base supramolecular complexes

Three acid-base compounds with supramolecular architectures, namely, (1,2-H2bdc)(dmt) (1), (trans-1,4-H2ccdc)0.5(phdat) (2) and (1,3-H2bdc)(phdat) (3) (1,2-H2bdc = 1,2-benzenedicarboxylic acid, trans-1, 4-H2ccdc = trans-1, 4-cyclohexanedicarboxylic acid, 1,3-H2bdc = 1,3-benzenedicarboxylic acid, dmt = 2,4-diamino-6-methyl-s-triazine, phdat = 2,4-diamino-6-phenyl-s-triazine) have been synthesized and characterized by IR spectra, elemental analyses, single-crystal X-ray diffractions and TGA.
