N2 - The metalation of triphenylmethane (Ph3CH) with potassium metal in toluene and PMDTA (N,N,N′N″,N″-pentamethyldiethylenetriamine) at 111 °C affords red crystals of [Ph3CK · PMDTA]n (1). X-ray analysis reveals that the single crystal structure of 1 is different to the one shown previously. Here a polymeric zigzag chain instead of a discrete molecule was observed. Crystal data (Mo Kα radiation) at -100 °C for 1: a = 9.872(2), b = 18.917(4), c = 29.047(6)Å, β = 97.63(3)°, monoclinic space group Cc, R = 0.0449 (F2 > 2σ(F2)), wR2 = 0.1420.
