Rare organometallic complexes can be stabilized by using an N-confused system as a carbon ligand. A stable organocopper(II) compound of N-confused calix[4]phyrin has been characterized by X-ray crystallography. Complete π conjugation was found not to be a prerequisite for the formation of the metal-carbon bond.

Abstract A zinc(II) complex of N-confused calix[4]phyrin (isoporphyrin) (2-Zn) has been synthesized and the structure was revealed by 1 H NMR and X-ray analyses. The atomic distance between zinc metal and the inner-core carbon was about 0.2 A longer compared with that of zinc(II) N-confused porphyrin complexes, suggesting the weaker side-on η1-coordination with the inner-core-carbon in 2-Zn.

The change of the axial bond length in the antimony(V) N-confused tetraphenylporphyrin dibromide complex was demonstrated by protonation and confirmed from X-ray single crystal analyses.
