2,2′-(1,4-Phenyl­ene)bis­(propane-2,2-di­yl) bis­(benzodi­thio­ate)

The title compound, C₂₆H₂₆S₄, shows a dihedral angle of 76.64 (15)° between the central and peripheral benzene rings. An inversion center is located at the centroid of the thio­benzoyl ring. In the crystal, weak C—H...S inter­actions form C(5) chains along [001]. There are no classical hydrogen bonds.

fac-[1,2-Bis(pyridin-4-yl)ethane-κN]tricarbon­yl(1,10-phenanthroline-κ²N,N′)rhenium(I) hexa­fluorido­phosphate aceto­nitrile monosolvate

The asymmetric unit of the title compound, [Re(C₁₂H₈N₂)(C₁₂H₁₂N₂)(CO)₃]PF₆.·CH₃CN, contains one cation, one hexa­fluorido­phosphate anion and one aceto­nitrile solvent mol­ecule. The Re^I ion is coordinated by two N atoms from the 1,10-phenanthroline ligand and one N atom from the 1,2-bis­(pyridin-4-yl)ethane ligand [mean Re—N = 2.191 (15) Å] and by three carbonyl ligands [mean Re—C = 1.926 (3) Å] in a distorted octa­hedral geometry.

In the title thia­zolidine-4-one derivative, C₂₀H₂₁NO₆S, the central thia­zolidine ring is essentially planar (r.m.s. deviation for all non-H atoms = 0.0287 Å) and forms a dihedral angle of 88.25 (5)° with the meth­oxy-substituted benzene ring and 74.21 (4)° with the 1,3-benzodioxole ring. The heterocyclic ring (with two O atoms) fused to benzene ring adopts an envelope conformation with the non-ring-junction C atom as the flap. In the crystal, the mol­ecules are linked into chains along [001] through weak C—H...O inter­actions, forming R⁴₄(28) edge-fused rings.

In the title compound, C₁₀H₆N₄O₅S, the mean plane of the non-H atoms of the central amide fragment C—N—C(=O)—C [r.m.s. deviation = 0.0294 Å] forms dihedral angles of 12.48 (7) and 46.66 (9)° with the planes of the thia­zole and benzene rings, respectively. In the crystal, mol­ecules are linked by N—H...O hydrogen bonds, forming chains along [001]. In addition, weak C—H...O hydrogen bonds link these chains, forming a two-dimensional network, containing R⁴₄(28) ring motifs parallel to (100).

In the title compound, C₁₃H₁₀BrNO₂, the mean plane of the non-H atoms of the central amide C—N—C(=O)—C fragment (r.m.s. deviation = 0.004 Å) forms a dihedral angle of 73.97 (12)° with the hy­droxy-substituted benzene ring and 25.42 (19)° with the bromo-substituted benzene ring. The two aromatic rings are inclined to one another by 80.7 (2)°. In the crystal, mol­ecules are linked by O—H...O and N—H...O hydrogen bonds, forming chains along [010]. The chains are linked by weak C—H...O hydrogen bonds, forming sheets parallel to (100), and enclosing R³₃(17) and R³₂(9) ring motifs.
