The 11 Ga(III)1 system yielded [Ga(PP-PP)-PC]+ and [Ga(PP)2-MC]+. Neither [Zr(PP-PP)-PC]2+ nor [Zr(PP)2-MC]2+ was detected in the 11 Zr(IV)1 system. Instead, the Zr(IV) system showed the formation of a 12 Zr(IV)1 pre-complex [Zr(PP-PP)2-PC], which following in situ amide bond forming chemistry, generated two Zr(IV) macrocyclic complexes with distinct architectures a dimer-of-dimers complex [Zr((PP)2)2-MC] and an end-to-end macrocycle [Zr(PP)4-MC]. The formation of [Fe(PP)2-MC]+, [Ga(PP)2-MC]+ or [Zr((PP)2)2-MC] was confirmed from reco
