Na+-Mediated aggregation of imino-carboxylate transition metal complexes

Abstract

The imino-carboxylate complexes [M(L)]⁻ (M = Mn, Ni) form the polymers {[Mn(L)]₂Na₄Cl₂·13H₂O}_∞ and {[Ni(L)]₂Na₄(BF₄)₂}_∞ in the presence of Na⁺; the degree of aggregation can be controlled by variation of the counter-anion and the amount of Na⁺ present, the Na⁺ ions forming sandwiched layers between aggregates of [M(L)]⁻.
