Reaction of octaethylporphyriniron(III) perchlorate, Fe(oep)ClO4, or a
n iron capped porphyrin perchlorate, Fe(C2cap)ClO4, with a copper(II)
imidazolate complex, CuIm, gives the imidazolate bridged dinuclear mon
oadducts, [Fe(oep)CuIm]ClO4 or [Fe(C2CaP)CuIM]ClO4, Which are characte
rized by variable temperature magnetic susceptibility as spin coupled
intermediate spin and admixed intermediate spin systems, respectively.
