The title polymeric compound, {[MnHg(SCN)4(H2O)]-C4H8O2S}n, consists of slightly distorted MnN4O2 octahedra and HgS4 tetrahedra. Each MnII ion is bound to N atoms belonging to the thiocyanate (SCN) groups and to two O atoms of adjacent water ligands. The sulfolane molecule connects with the coordinated water molecule through hydrogen bonding. Each HgII atom is coordinated by four SCN S atoms. The two adjacent MnII atoms and two O atoms of bridging water molecules connect with one another and form a parallelogram. Each pair of MnII and HgII atoms is connected by an -SCN- bridge, forming an infinite three-dimensional structure. [ABSTRACT FROM AUTHOR]

In the title compound, C7H11O3PS4, the five-membered ring is in an envelope conformation. The average values of the S—C sp3 and S—C sp2 bond lengths are 1.813 (6) and 1.755 (8) Å, respectively. The crystal packing is stabilized by weak inter­molecular C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title complex, [ZnCl(C4H8N2S)3]Cl, comprises [ZnCl(ATU)3]+ cations (ATU is allyl­thio­urea) and Cl− anions, both of which lie on threefold axes. The three S atoms of the allyl­thio­urea mol­ecules and one Cl atom coordinate the Zn atom in a tetrahedral arrangement. The crystal packing is mainly determined by weak N—H⋯Cl hydrogen bonds.

The title compound, C15H11ClN2S, has been prepared by the reaction of Lawesson's reagent with N-(2-chloro­benzoyl)- N′-(4-methyl­benzoyl)­hydrazine, under microwave irradiation and in the absence of solvent. It crystallizes with two mol­ecules per asymmetric unit and X-ray analysis reveals that the three rings in both mol­ecules are nearly coplanar. The mol­ecules form stacks, in a head-to-tail manner, with intermolecular π–π interactions. Intermolecular C—H⋯N hydrogen bonds are also present. [ABSTRACT FROM AUTHOR]

The title complex, C6H15N4O2+·C4H3O4−·2H2O, contains a planar ring formed by sharing one H atom between the O atoms in the carboxyl groups of the maleate anion. This hydrogen bond is slightly asymmetric. In thel-argininium(+) cation, both the α-amino and the guanidyl groups are protonated. The nonlinear optical response of the compound is derived from the intrinsic hyperpolarizabilities of thel-argininium cations, maleate anions and intermolecular hydrogen bonds.

In the title complex, (C6H8N)2[Zn(dmit)2] (dmit is 2-thioxo-1,3-dithiole-4,5-dithiol­ate, C3S5), each Zn atom is coordinated by four dmit S atoms that define a distorted tetra­hedral arrangement. The crystal structure is stabilized by C—H⋯S hydrogen bonding and S⋯S contacts. [ABSTRACT FROM AUTHOR]

The title complex, [Zn(C2H8N2)3][Zn(C4N2S2)2], exists as discrete ions, both of which lie on twofold rotation axes. The [Zn(C2H8N2)3]2+ cation exhibits a slightly distorted octahedral geometry. In the [Zn(C4N2S2)2]2− anion, the ZnII atom is surrounded by two chelating ligands in a distorted tetrahedral geometry. The crystal structure is stabilized by hydrogen bonds of the types N—H⋯N and N—H⋯S. [ABSTRACT FROM AUTHOR]

The title molecule, C26H46O4, has symmetry. The non-H atoms of the octyloxy and methoxymethyl chains are almost coplanar with the benzene ring. There are weak C—H...O hydrogen bonds and C—H...π-ring interactions in the structure. The molecules are loosely packed in the structure. The unit-cell volume is 20% larger than is expected from the empirical rule pertinent to organic compounds, which states that the unit-cell volume (Å3) is approximately equal to the number of non-H atoms in the unit cell multiplied by 18.

In the crystal structure of the title phospho­nium salt, C22H22O2P+·Br−·H2O, the triphenyl­phospho­sphonium group has three P—C bonds to phenyl rings which are equal within experimental error [mean 1.782 (3) Å] The P atom is also attached directly to the C atom of a 1,3-dioxan-2-ylmethyl group with a longer P—C bond of 1.800 (3) Å. The C—C bond of the dioxane ring [1.418 (5) Å] is shorter than the normal bond distance. The asymmetric unit contains two bromide anions on twofold rotation axes to balance the charge of the cation.

The molecules of the title compound, C11H13N3O3, are linked by O—H⋯N and N—H⋯O interactions into a linear hydrogen-bonded chain. [ABSTRACT FROM AUTHOR]
