In the title compound, (C12H25NH3)2[Cu(C6Cl2O4)2(C2H5OH)2], the CuII atom lies on a crystallographic inversion center and is coordinated in a distorted octahedral geometry by four O atoms of two chloranilate ligands and two O atoms of two ethanol molecules which are trans to each other in the axial positions. In the crystal, the CuII mononuclear dianions are linked by O—HO hydrogen bonds into a tape along the a-axis direction. The tapes are linked through N—HO hydrogen bonds between the dianion and the n-dodecylammonium cation, forming a two-dimensional network parallel to the ab plane.

In the title coordination polymer, [Mn(C6Cl2O4)(C2H5OH)2]n, the MnII atom and the chloranilate [systematic name: 2,5-dichloro-3,6-dioxocyclohexa-1,4-diene-1,4-bis(olate)] ion lie on crystallographic inversion centers. The geometry around the MnII atom is a distorted octahedron involving four O atoms of two chloranilate ions and two O atoms from two ethanol molecules. The chloranilate ion serves as a bridging ligand between the MnII ions, leading to an infinite linear chain along the b-axis direction. The chains are linked by O—HO hydrogen bonds between the apically coordinating ethanol molecule and the chloranilate ion, affording a two-dimensional layer expanding parallel to the ab plane.

The title complex, [Co(C21H16N4)2][Co(NCS)4]·CH3OH, consists of one [Co{C(py)4}2]2+ complex cation [C(py)4 = tetrakis(pyridin-2-yl)methane], one [Co(NCS)4]2− complex anion and a methanol solvent molecule. In the cation, the CoII atom is coordinated by six N atoms of two C(py)4 ligands in a distorted octahedral geometry. In the anion, the CoII atom is coordinated by the N atoms of four NCS− ligands in a distorted tetrahedral geometry. The methanol molecule is disordered and was modelled over three orientations (occupancies 0.8:0.1:0.1). There are two weak hydrogen-bond-like interactions between the methanol solvent molecule and NCS− ligands of the anion [OS = 3.283 (3) and 3.170 (2) Å].
