Porphyrazine compounds having moieties substituted at the eight peripheral .beta.-pyrrole positions are disclosed. The porphyrazine compounds have the general structural formula: ##STR1## wherein M is H.sub.2 or a metal capable of complexing with the pyrrole nitrogen atoms, and A, B, C and D are independently selected from the group consisting of a thio moiety, an amino moiety, an oxo moiety, a phospho moiety, a seleno moiety, a telluro moiety and a non-coordinating moiety, like a hydrocarbon moiety, with the proviso that not all of A, B, C and D are a thio moiety and that not all of A, B, C, and D are a hydrocarbon moiety. The porphyrazine compounds, depending on the identity of A, B, C and D, are capable of complexing one to four metal ions to the periphery of the porphyrazine to form a multimetallic porphyrazine. Multimetallic porphyrazine compounds can be linked by the peripherally-complexed metal ions to form a linear, i.e., ribbon, polymer or a two-dimension, i.e., sheet polymer. The porphyrazine compounds, and the multimetallic complexes and polymers derived therefrom, are useful in, or as, magnet materials, molecular metal conductors, pharmaceuticals, imaging agents, and dyes.
