In the title compound, [Mo3(CH3COO)(C4H10O2PS2)3S4(C10H8N2)]·C4H10O, the complex mol-ecule has a trinuclear incomplete cuboidal structure which is coordinated by three kinds of ligands, namely, diethyl di-thio-phosphate, acetate and 4,4'-bipyridyl. If Mo-Mo bonds are ignored, each Mo atom can be considered as six-coordinated in a distorted octa-hedral geometry. The Mo-Mo distance of 2.6880 (5) ...

A novel inorganic-organic hybrid supramolecular macrocyclic compound, (4-nitroanilinium) (18-crown-6)(PF6)(1), was synthesized and characterized by infrared spectroscopy, thermogravimetric analysis, elemental analysis, differential scanning calorimetry (DSC), and single-crystal X-ray diffraction. Crystal 1 is found to comprise 1D C–H···F–P hydrogen-bonded chains of (4-nitroanilinium+) (18-crown...

Despite the simple chemical formula, [Ni(1,10-phenanthroline)2(H2O)2](NO3)2, crystallizes with a remarkably complicated 3-D hydrogen bonding supramolecular assembly. The title compound crystallizes in the monoclinic space group P21/c, with an unusually long b axis and a large cell volume. A huge asymmetric unit has been identified, containing six discrete [Ni(1,10-phen)2(H2O)2] 2+ cations and t...

The crystal structure of (4-methylcyclohexylammonium)2[CuBr4], 1, belongs to the monoclinic system, space group P21/n with cell constants a = 8.1687(2) Ǻ, b = 12.1569(3) Ǻ, c = 22.3921(3) Ǻ, β = 94.8290(10)°, Z = 4. The structure was solved by direct methods and refined to R = 0.0685 (wR2 = 0.1287). The structure analysis reveals that the Cu(II) has an intermediate geometry between regular tetr...

Easy access to a class of chiral gelators has been achieved by exploiting primary ammonium monocarboxylate (PAM), a supramolecular synthon. A combinatorial library comprising of 16 salts, derived from 5 L-amino acid methyl esters and 4 cinnamic acid derivatives, has been prepared and scanned for gelation. Remarkably, 14 out of 16 salts prepared (87.5 % of the salts) show moderate to good gelati...

In the title complex, [Zn(C(10)H(12)NO(2))(2)(H(2)O)]·H(2)O, the Zn(II) ion is coordinated by two N and two O atoms from two 5-n-butyl-pyridine-2-carboxyl-ato ligands and one O atom from a water mol-ecule in a distorted square-pyramidal geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds link mol-ecules into a two-dimensional supramolecular structure parallel to (001).

The title compound, C14H13N3O3·H2O, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the lattice water molecule plays a major role in the supramolecular architecture by interconnecting adjacent molecules into a three-dimensional netwrok by means of O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bondi...

In the structure of the title compound, C8H6Br2O4, the complete mol-ecule is generated by the application of a centre of inversion. The mol-ecule is planar (r.m.s. deviation for all non-H atoms but methyl C = 0.0358 Å), with only the methyl groups being deviated from the plane [by ±0.321 (4) Å]. In the crystal packing, Br⋯O(methoxy) halogen bonds [3.2407 (19) Å] connect molecules into supramole...

In the title compound, C(12)H(9)NOS, the sulfoxide O atom is disordered over two sites with occupancies of 0.907 (4) and 0.093 (4). The dihedral angle betweeen the two aromatic rings is 18.40 (14)°. Different types of supramolecular interactions including inter-molecular N-H⋯O hydrogen bonds and π-π contacts [centroid-centroid distances = 3.9096 (16) and 4.1423 (16) Å] between the aromatic ring...
