Abstract

Crossing the line: A pH-induced "crossover" in 3D shapes of supramolecular constructs derived from trans(NH3)2Pt(II), [Pd(II)(en)], and the purine model nucleobase 9-methylhypoxanthine (see figure) is reported in which [Pd(en)(H2O)](2+) and [Pd(en)(OH)](+) are the decisive players (en = ethylenediamine).

Keywords: anion binding; host-guest systems; metallacycles; nucleobases.
