The multimodal ligand hexakis(2-pyridyloxy)cyclotriphosphazene (L) and its 4-methyl-2-pyridyloxy analogue (MeL) react with Ag(I) to afford [AgL](+)}(infinity) supramolecular cationic columns via self-assembly, with the anions occupying the intercolumnar channels. In contrast, the reaction of MeL with Cu(I) yields a dimetallic Cu(II) complex containing mu-OH and mu-4-methyl-2-pyridyloxylato bridges.

phosphazene ring and two halide ions. For the cobaltcomplex the pyridyloxy groups are cisoid and for the nickel complex they are transoid. The dimetallic complexes, [Co(MeL)X}CoX3] (X = Cl or Br) are zwitterionic with one cobalt atom in a rhombic coordination sphere with the ligand acting as κ5N donor binding to the metal through the nitrogen atoms of four pyridyloxy pendant arms, phosphazene nitrogen

all three structures as a consequence of the phenoxy-hinge, which links the pyridine pendant donors to the cyclotriphosphazene platform, allowing the formation of six-membered chelate rings. The spectroscopic (mass spectral, EPR and electronic) and magnetic properties of the complexes are discussed. The EPR and variable temperature magnetic susceptibility results for the dicopper complex, [(CuCl(2))(2)(MeL)]
