Resumo

Crossing the line: A pH-induced “crossover” in 3D shapes of supramolecular constructs derived from trans(NH3)2PtII, [PdII(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).
