Abstract: The combination of four iso-nicotinate appended tetrathiacalix[4]arene (TCA-1) in 1,2-alternate imposed conformation behaving as neutral tectons with Co(II)Cl₂ and Hg(II)Cl₂ metallic salts, leads to the formation of neutral, new coordination networks. Indeed, the tetrasubstituted TCA-1 derivative leads to a 1D coordination polymer with Co(II)Cl₂ and a 2D grid-like network with, Hg(II)Cl₂. The effect of the nature of the metal used on the dimensionality was demonstrated by X-ray diffraction studies on a single crystal.
