3,14-Dimethyl-2,6,13,17-tetra­aza­tricyclo­[16.4.0.0^7,12]docosa­ne–(naphthalen-1-yl)methanol (1/2)

In the title co-crystal, C₂₀H₄₀N₄·2C₁₁H₁₀O, the macrocycle is generated by a crystallographic inversion centre. The N atoms show a pyramidal coordination, and the cyclo­hexane ring that is fused to the 14-membered C₁₀N₄ ring exists in a chair conformation, whereas the methyl substituent occupies an axial site. The (naphthalen-1-yl)methanol mol­ecule forms an O—H...N hydrogen bond to a cyclam N atom. The mean-square-plane passing through the 14-membered ring is approximately coplanar with the naphthalene fused-ring [dihedral angle = 6.6 (1)°].

{3,14-Dimethyl-2,6,13,17-tetra­aza­tricyclo­[16.4.0.0^7,12]docosane-κ⁴N,N′,N′′,N′′′)bis­(nitrato-κO)copper(II)

The Cu^II atom in the title compound, [Cu(NO₃)₂(C₂₀H₄₀N₄)], is N,N′,N′′,N′′′-chelated by the macrocyclic ligand: the four N atoms form a square, above and below which are located the O atoms of the nitrate ions. The metal atom exists in a tetra­gonally distorted octa­hedron, on a special position of site symmetry. One of the amino groups is hydrogen bonded to an O atom of the nitrate ion. The other amino group is hydrogen bonded to O atom of an adjacent mol­ecule, generating a supra­molecular dimeric hydrogen-bonded dinuclear aggregate.

In the title compound, [CrCl₂(C₃H₁₀N₂)₂]₂[ZnCl₄], the Cr^III atom is coordinated by four N atoms of propane-1,3-diamine (tn) and two Cl atoms in a trans arrangement, displaying a distorted octa­hedral geometry with crystallographic inversion symmetry; the Zn atom in the [ZnCl₄]²⁻ anion lies on a -4 axis. The orientations of the two six-membered chelate rings in the complex cation are in an anti chair–chair conformation with respect to each other. The Cr—N bond lengths are 2.087 (6) and 2.097 (6) Å. The Cr—Cl and Zn—Cl bond lengths are 2.3151 (16) and 2.3255 (13) Å, respectively. Weak inter­molecular hydrogen bonds involving the tn NH₂ groups as donors and chloride ligands of the anion and cation as acceptors are observed.
