The article describes the crystal structure of 5-(4,5-ethylenedithio-1,3-dithiol-2-yl-idene)-1,3,4,6-tetrathiapentalen-2-one (EDTO-TTP) and 5-[4,5-(ethene-1,2-diyldithio)-1,3-dithiol-2-ylidene]-1,3,4,6-tetrathiapentalen-2-one (VDTO-TTP). It shows the planar conformation adopted by EDTO-TTP molecule as well as the similarity of the bond characteristics of both compounds. Also reported is the intermolecular interactions exhibited by the EDTO-TTP crystal structure, including transverse and longitudinal interactions, and hydrogen bonding.

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]

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 compound, C13H6O4S5, possesses crystallographically imposed mirror symmetry, with the atoms of the C=S group lying on the mirror plane. It is an example of the general formula [ RCO]2(dmit), where R is a furan ring and dmit is 2-thioxo-1,3-dithiole-4,5-dithiol­ate. The components exhibit some polarization of their mol­ecular–electronic structure. The dmit and furan moieties exhibit a high degree of conjugation, as the introduction of C=O connecting the conjugated furan (donor) and dmit (acceptor) rings forms a good conjugated system with high delocalization. A polar three-dimensional framework is built from a combination of inter­molecular contacts, namely S⋯S inter­actions and C—H⋯O hydrogen bonding. The structural characteristics lead to good second-order non-linear optical properties. [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 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]
