HgCl2 and CdCl2 form 1:1 complexes with 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6). The complexes are isostructural. The metal coordination is hexagonal bipyramidal, with chlorine atoms strongly coordinated in the axial positions and the 18-crown-6 in the equatorial place. The symmetry of the complex is crystallographically required to be [Formula: see text], but is very nearly [Formula: see text]. The Hg—Cl, Hg—O, Cd—Cl, and Cd—O distances are 2.314(1), 2.825(4), 2.3645(5), and 2.752(1) Å, respectively. Crystals of HgCl2•18-crown-6 are rhombohedral, space group [Formula: see text], a = 7.746(2) Å, α = 95.26(3)°, Z = 1 unit of HgCl2C12H24O6, R = 0.026 for 543 independent reflections with θ < 25°, I > 3σ(I). Crystals of CdCl2•18-crown-6 are also rhombohedral, space group [Formula: see text], a = 7.712(3) Å, α = 95.57(2)°, Z = 1 unit of CdCl2C12H24O6, R = 0.022 for 534 independent reflections with θ < 25°, I > 3σ(I).

Porous Coordination Polymer

Porous coordination polymer compounds consisting of Zn2+, 1,2-di(4-pyridyl)ethane, and dicarboxylates were synthesised and their crystal structures were determined. These are doubly interpenetrated 2D layer structures, and the flexibility of porous structures is dependent on the substituent group of the dicarboxylate. From gas adsorption studies, distinct adsorption isotherms were observed for CO2, CH4, C2H4, and C2H6 at 195 K and 273 K, respectively.
