Crystal structure of {4-[10,15,20-tris(4-methoxy-phenyl)porphyrin-5-yl]benzyl 2-diazoacetato}-zinc(II)

Abstract : In the title compound, [Zn(CHNO)], the Zn cation is chelated by four pyrrole N atoms of the porphyrinate anion and coordinated by a symmetry-generated keto O atom of the diazo-ester group in a distorted square-pyramidal geometry. The mean Zn-N(pyrrole) bond length is 2.058 Å and the Zn-O(diazo-ester) bond length is 2.179 (4) Å. The zinc cation is displaced by 0.2202 (13) Å from the NC mean plane of the porphyrinate anion toward the O atom; the involvement of this atom leads to a [100] polymeric chain in the crystal.
