4-Methyl-N-(4-methyl­phenyl­sulfon­yl)-N-[4-(4-methyl­phen­yl)-1,3-thia­zol-2-yl]benzene­sulfonamide

There are two independent mol­ecules in the asymmetric unit of the title compound, C₂₄H₂₂N₂O₄S₃. In each, the sulfonamide N atoms reveal nearly a trigonal-planar geometry with two S atoms of the O=S=O groups and one C atom of the thia­zole ring; the angles around the N atoms are between 117.00 (13) and 123.86 (9)°. The methyl­phenyl­sulfonyl groups are in anti conformations, forming dihedral angles of 78.00 (7)/72.53 (5) and 77.09 (6)/71.50 (7)° with the trigonal S—N—S planes in the two mol­ecules. The thia­zole groups are rotated around the C—N bonds and are almost perpendicular to the S—N—S plane [dihedral angles of 78.00 (7)/72.53 (5) and 77.09 (6)/71.50 (7)°]. In the crystal, pairs of C—H...O inter­actions, with the O atoms of the sulfonamide groups as acceptors, link each of the independent mol­ecules into inversion dimers.

Di­chlorido­(4,4′-di-tert-butyl-2,2′-bi­pyridine-κ²N,N′)palladium(II) dimethyl sulfoxide monosolvate monohydrate

The title compound, [PdCl₂(C₁₈H₂₄N₂)]·(CH₃)₂SO·H₂O, the Pd^II ion is in a distorted square-planar geometry. The Pd—N bond distances are 2.022 (2) and 2.027 (2) Å, the Pd—Cl bond distances are 2.2880 (7) and 2.2833 (7) Å, and the ligand bite angle is 80.07 (9)°. The dimethyl sulfoxide and water mol­ecules form linear chains along [100] by O—H...O and O—H...S hydrogen bonds, generating eight- and 12-membered rings. C—H...Cl inter­actions link the chains, forming a three-dimensional arrangement. In addition, the 4,4-di-tert-butyl-2,2′-bi­pyridine ligand exhibits π–π stacking inter­actions [centroid–centroid distances = 3.8741 (15) and 3.8353 (15) Å]. The DMSO solvent is disordered and was refined with an occupancy ratio of 0.866 (3):0.134 (3).

(2,2′-Bi­pyridine-κ²N,N′)di­chloridopalladium(II) 1,4-dioxane hemisolvate

The asymmetric unit of the title compound, [PdCl₂(C₁₀H₈N₂)]·0.5C₄H₈O₂, consists of one Pd^II complex mol­ecule and a half-mol­ecule of 1,4-dioxane, the complete mol­ecule being generated by inversion symmetry. The Pd^II atom has an almost square-planar coordination formed by the 2,2′-bi­pyridine ligand and two chloride ligands. Two intra­molecular C—H...Cl hydrogen bonds occur. In the crystal, the Pd^II complex and 1,4-dioxane mol­ecules are connected by C—H...O hydrogen bonds, forming a layer parallel to (10-1). Within the layer, weak π–π inter­actions [centroid–centroid distance = 3.817 (4) Å] are observed between the pyridine rings.

Bis(2-amino-4-phenyl-1,3-thia­zol-3-ium) tetra­chlorido­palladate(II)

The title compound, (C₉H₉N₂S)₂[PdCl₄], consists of two monoprotonated 2-amino-4-phenyl-1,3-thia­zole molecules and one tetra­chlorido­palladate anion. The organic molecules exhibit a dihedral angle between the main rings planes of 31.82 (9)°. In the anion, the Pd^II atom is located on a crystallographic centre of symmetry with a square-planar geometry. In the crystal, the anions and cations are connected through bifurcated N—H...Cl hydrogen bonds, and these inter­actions lead to hydrogen-bonded tapes of cations and anions along [100].

(tert-But­yl)(2-hy­droxy­eth­yl)ammonium chloride

In the cation of the title mol­ecular salt, C₆H₁₆NO⁺·Cl⁻, the N—C—C—O torsion angle is 176.5 (2)°. In the crystal, the cations and chloride ions are linked by N—H...O and O—H...O hydrogen bonds, generating a two-dimensional network parallel to (100).
