The mixed-valent copper thiol­ate complex hexa­kis­{μ₃-2-[(1,3-dimethyl­imidazol­idene)amino]­benzene­thiol­ato}dicopper(II)tetra­copper(I) bis­(hexa­fluoridophosphate) acetonitrile disolvate dichloro­methane disolvate

The mol­ecular structure of the title compound, [Cu₄^ICu₂^II(C₁₁H₁₄N₃S)₆](PF₆)₂·2CH₃CN·2CH₂Cl₂, shows a mixed-valent copper(I/II) thiol­ate complex with a distorted tetra­hedral coordination of the Cu^I and Cu^II cations by one guanidine N atom and three S atoms each. Characteristic features of the Cu₆S₆ skeleton are a total of six chemically identical μ₃-thiol­ate bridges and almost planar Cu₂S₂ units with a maximum deviation of 0.110 (1) Å from the best plane. Each Cu₂S₂ unit then shares common Cu–S edges with a neighbouring unit; the enclosed dihedral angle is 60.14 (2)°. The geometric centre of the Cu₆S₆ cation lies on a crystallographic inversion centre. Cu—S bond lengths range from 2.294 (1) to 2.457 (1) Å, Cu—N bond lengths from 2.005 (3) to 2.018 (3) Å and the non-bonding Cu...Cu distances from 2.5743 (7) to 2.5892 (6) Å. C—H...F hydrogen-bond inter­actions occur between the PF₆⁻ anion and the complex mol­ecule and between the PF₆⁻ anion and the acetonitrile solvent mol­ecule.

Triethyl­ammonium 4-(3,5-dinitro­benzamido)-N-(3,5-dinitro­benzo­yl)benzene­sulfonamidate

The mol­ecular structure of the title salt, C₆H₁₆N⁺·C₂₀H₁₁N₆O₁₂S⁻, shows a planar geometry of the benzamido–phen­yl–sulfonyl moiety, with a dihedral angle of 1.59 (9)° between the aromatic ring planes. The central ring and the aromatic ring of the other dinitro­benzamide group are nearly perpendicular, making a dihedral angle of 89.55 (9)°. All nitro groups lie almost in plane with the associated aromatic rings, the O—N—C—C torsion angles ranging from 9.2 (2) to 24.3 (2)°. In the crystal, strong anion–anion N—H...O and anion–cation hydrogen bonds form inversion dimers stacked along the a axis. Less prominent anion–anion C—H...O inter­actions lead to the formation of a three-dimensional network including anion–anion dimers as well as anion–anion chains along [100?].
