Bis­(3-methyl-1-propyl-1,3-di­hydro-1H-imidazol-2-yl­idene)silver(I) chlor­ido(5,10,15,20-tetra­phenyl­porphin­ato)cadmate(II)

The title compound consist of a cadmium(II) porphyrin with an axial chloride ligand and a silver(I) carbene.

4,4'-(Ethene-1,2-diyl)dipyridinium bis­(2-hy­droxy-3-meth­oxy­benzoate)

In the title mol­ecular salt, the components are linked by N—H⋯O and C—H⋯O hydrogen bonds.

(Phenyl­iodos­yl)benzene tosyl­ate dihydrate

The title compound is a λ⁵-di­aryl­iodosyl salt capable of sulfide oxidations.

1,1′-Methyl­enebis(4,4′-bipyridin-1-ium) dibromide

The asymmetric unit of the title salt comprises half of the mol­ecule and a bromide ion. The chevron-shaped cations stack as columns that are stabilized by through space electrostatic inter­actions and inter­columnar hydrogen bonding.

1,1′-Methyl­enebis{4-[(E)-2-(pyridin-4-yl)ethen­yl]pyridinium} dibromide dihydrate

Cations of the title compound inter­act via π–π inter­actions and hydrogen bond with water to form a zigzag ribbon.
