Abstract

Two different hydrate phases, namely, {[Cu(mal)2](picH) 2·2H2O}n (1) and {[Cu(mal) 2](picH)2·5H2O}n (2) [malH2 = malonic acid; picH = protonated 2-amino-4-picoline] could be synthesized from purely aqueous media simply by mixing the reactants in stoichiometric ratio but with a slight alteration in the acidity of the reaction media. When the solid-state structure of 1 is compared with the previously reported complex 2, interesting changes in the supramolecular self-assembly are noticed. We found that the observed pH-triggered change is exclusive in the ternary system stated and not for Ni(II), Co(II) or Mn(II). We also noticed the presence of a -CH3⋯Ow interaction between the methyl terminals of protonated picoline molecules and the oxygen atoms of lattice water molecules in 1.
