Bis[3,3-dimethyl-2-(2-oxoethyl­idene)indolinyl-κ2 N,O]palladium(II)

The asymmetric unit of the title compound, [Pd(C12H12NO)2], consists of three crystallographically independent half-mol­ecules. Each PdII atom lies on a center of inversion and is four-coordinated by two monoanionic forms of the amino­acryl­aldehyde in a square-planar geometry. In the crystal, adjacent mol­ecules are connected through C—H⋯π and C—H⋯O inter­actions into a three-dimensional polymeric structure

Bis{μ-N′-[1-(5-bromo-2-oxidophen­yl)ethyl­idene]benzene­sulfono­hydrazidato}-κ3 O 2,N′:N;κ3 N:O 2,N′-bis­[(dimethyl sulfoxide-κO)copper(II)]

In the title centrosymmetric dinuclear complex, [Cu2(C15H11BrN2O3S)2(C2H6OS)2], the CuII ion is N,O-chelated by a dianionic ligand, monocoordinated by the sulfonamide N atom of a symmetry-related ligand and coordinated by an O atom from a dimethyl sulfoxide ligand, forming a distorted square-planar coordination geometry

2-[(3,5-Di-tert-butyl-4-hy­droxy­benz­yl)sulfan­yl]benzoic acid

In the title compound, C22H28O3S, the dihedral angle between the two aromatic rings is 80.56 (6)°. The hy­droxy group is shielded by the two sterically hindered tert-butyl groups and therefore is not involved in any hydrogen bonding. The C—O—H fragment is coplanar with the aromatic ring, the dihedral angle between them being 7(5)°. In the crystal structure, pairs of mol­ecules are hydrogen bonded across crystallographic centers of symmetry

2-[2-(1H-indol-3-yl)ethyl­iminiomethyl]-4-nitro­phenolate

The title Schiff base, C17H15N3O3, exists in the zwitterionic form with the phenol H atom transferred to the imine group. Adjacent zwitterions are linked into a linear chain running along the a axis by an indole–hydr­oxy N—H⋯O hydrogen bond [3.100 (2) Å]

N′-(5-Fluoro-2-oxo-2,3-dihydro-1H-indol-3-yl­idene)benzene­sulfono­hydrazide

The mol­ecule of the title compound, C14H10FN3O3S, consists of an indole unit and a phenylsulfonyl unit that are disposed in an approximately trans orientation relative to the N—N single bond. Two mol­ecules are arranged about a center of inversion, forming a hydrazide–carbonyl N—H⋯O hydrogen-bonded dimer; the dimers are linked by an indole–sulfonyl N—H⋯O hydrogen bond into a ribbon

N′-(2-Hydr­oxy-5-nitro­benzyl­idene)-2-(1H-indol-3-yl)acetohydrazide

The mol­ecule of the title compound, C17H14N4O4, uses its amide –NH– group to form a hydrogen bond to the amido –C(=O)– group of an adjacent mol­ecule to furnish a linear chain structure. The hydr­oxy group forms an intra­molecular hydrogen bond; the indolyl –NH– unit does not engage in any strong hydrogen-bonding inter­actions

Bis[1,5-bis­(1H-indol-3-ylmethyl­ene)thio­carbazonato-κ2 N,S]nickel(II) dimethyl sulfoxide disolvate

The Ni atom in the crystal structure of the centrosymmetric title compound, [Ni(C19H15N6S)2]·2C2H6OS, is N,S-chelated by the deprotonated Schiff bases in a square-planar geometry. The –CH=N—N=C(S)—NH—N=CH– frament is planar. The two indolyl –NH (donor) sites inter­act with dimethyl sulfoxide mol­ecules to furnish a layer motif

Bis{μ-2-(1H-indol-3-yl)-N′-[1-(5-methyl-2-oxidophen­yl)ethyl­idene]­aceto­hydraz­idato}bis­[aqua­zinc(II)] dimethyl sulfoxide tetra­solvate

The dinuclear title compound, [Zn2(C19H17N3O2)2(H2O)2]·4C2H6OS, lies about a center of inversion. The deprotonated monoanion O,N,O-chelates the Zn atom; the hydr­oxy O atom also engages in bonding to the symmetry-related Zn atom so that one N and three O atoms form a square around the metal. The coordination geometry is square-pyramidal, with the apical site occupied by a water mol­ecule. Hydrogen bonds, with the water mol­ecule serving as donor atom, lead to the formation of a linear chain motif. There is an N—H⋯O hydrogen bond between the complex molecule and solvent O atom

Bis{2-bromo-4-chloro-6-[2-(phenyl­sulfon­yl)hydrazonometh­yl]phenolato-κ2 N,O 1}copper(II)

The Cu atom in the title compound, [Cu(C13H9BrClN2O3S)2], is chelated by two deprotonated Schiff base ligands in a square-planar coordination geometry; the Cu atom lies on a center of inversion. The –NH– group of one anion forms an intra­molecular hydrogen bond to the phenolate atom of the symmetry-related ion

N′-[1-(2-Hydr­oxy-5-methyl­phen­yl)ethyl­idene]benzene­sulfonohydrazide

The two independent mol­ecules in the asymmetric unit of the title compound, C15H16N2O3S, are each linked by an N—H⋯Osulfon­yl hydrogen bond into a linear chain that runs along the shortest axis of the triclinic unit cell. The hydr­oxy groups are engaged in intra­molecular hydrogen bonding and the amino N atom shows pyramidal coordination
