Molecular Tectonics: high dimensional coordination networks based on a methylenecarboxylate appended tetramercaptothiacalix[4]arene in 1,3-Alternate conformation

Abstract

The combination, under mild conditions, of the methylenecarboxylic appended tetramercaptotetrathiacalix[4]arene (TMTCA) derivative 4, blocked in 1,3-Alternate conformation, with acetate salts of octahedral Copper(II), Manganese(II), Nickel(II) and Zinc(II), leads to the formation, in the crystalline state, of high dimensional coordination networks. Depending on the nature of the used metal cations and bases (pyridine or non-coordinating Et3N), six new different high-dimensional coordination polymers have been evidenced, presenting 4 different coordination patterns. All the compounds present a metal/4 ratio equal to 2/1. The formation of a 2D grid-like compound (4-Zn2(Py)4) as well as three different pseudo-diamandoid-like 3D compounds (4-Co2(Py)6(H2O), 4-Ni2(Py)6(H2O), 4-Mn2(Py)4(MeOH)2, 4-Mn2(DMF)2(MeOH)4 and 4-Zn2(MeOH)4) is observed.
