The crystal structure of a two-dimensional metal–organic compound constructed from 4,4′-bis­[(1H-imidazol-1-yl)meth­yl]-1,1′-biphenyl (BIMB) and nickel ions is described. Each BIMB ligand adopts a linear linker to connect Ni2+ ions, forming a layer with an sql network. In the crystal, neighboring layers repeat in an ABAB stacking mode, and weak inter­molecular C—H⋯Cl hydrogen bonds between alternate layers lead to a three-dimensional, twofold inter­penetrated, supra­molecular framework with a pcu topology net.

The central manganese(III) atom has a distorted square-pyramidal coordination environment, defined by the porphyrin N atoms in the basal plane and a nitrate O atom in the apical site.

In the title mol­ecular salt, 2C12H19N2O+·C4H2O42−·2C4H4O4, the components are held together by N—H⋯O and O—H⋯O hydrogen bonds, forming chains along [001].

In the title 1:2 co-crystal, C—I⋯N halogen bonds between one of the 1,2,3,5-tetra­fluoro-4,6-di­iodo­benzene mol­ecules and the 5-{[4-(di­methyl­amino)­phen­yl]ethyn­yl}pyrimidine mol­ecule form [110] chains while the second 1,2,3,5-tetra­fluoro-4,6-di­iodo­benzene mol­ecule resides in [100] channels.

The benzo­thia­zole and thio­phene rings are almost coplanar. The NH2 group forms intra­molecular hydrogen bonds. The Sgalactose—Cthio­phene bond is short. The mol­ecules are connected by two `weak' hydrogen bonds and a short N⋯S contact.
