Structure of zinc tetraphenylporphyrin dimethyl formamide-methylene chloride

C₄₈H₃₇N₅ZnOCl₂,M _r+836.13, triclinic, $P\bar 1$ ,a+11.2231(15),b+12.5155(18),c+14.6013(19)Å, α=99.001(7), β=94.600(8), γ=103.221(7)^o,V+1957.6(5)ų,Z+2, D_x+1.419 gcm^?3, MoKα (λ=0.7107Å), µ_cale,F(000)=1670,T+173±1K, final discrepancy factor 2.8% for 5274 unique reflections above 2.5σ(I) in the range 3<2θ<48^o. The metal is coordinated to the four nitrogen atoms of the porphyrin ring and the oxygen of the dimethyl formamide moiety. The geometry of this porphyrin is nonplanar with respect to the overall structure, although the pyrrole rings are nearly coplanar with the zine metal pulled out of the plane in the familiar domed-shaped geometry.
