1-D and 2-D coordination networks based on tetrathiacalix[4]arene derivative generated with mercury and cobalt salts

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)Cl 2 and Hg(II)Cl 2 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)Cl 2 and a 2D grid-like network with, Hg(II)Cl 2 . The effect of the nature of the metal used on the dimensionality was demonstrated by X-ray diffraction studies on a single crystal.
