With the iminopyridine-functionalized framework in hand, metalation proceeded smoothly with a variety of M(I) and M(II) salts (e.g., MnCl2, FeCl2, CoI2, NiCl2, NiBr2, CuCl) to generate 1-(IP)M-18% (Table ). The crystallinity of the metalated materials was confirmed by PXRD (Fig. ), and metalation was quantified by ICP analysis (Table ). While nearly all transition metals tested led to >90% metalation, a notable exception was Cu(II), which leached in acetonitrile and formed side products in methanol. Overall, this work establishes a remarkably general route to achieve bimetallic iminopyridine species with diverse metal cations.
