[meso-5,10,15,20-Tetra­kis(5-bromo­thio­phen-2-yl)porphyrinato-κ(4) N,N′,N′′,N′′′]nickel(II)

The Ni(II) atom in the title porphyrin complex, [Ni(C(36)H(16)Br(4)N(4)S(4))], is in a square-planar geometry defined by four pyrrole N atoms. There is considerable buckling in the porphyrin ring with the dihedral angles between the N(4) donor set and the pyrrole rings being in the range 17.0 (3)–18.8 (3)°. Each of the six-membered chelate rings is twisted about an Ni—N bond and the dihedral angles between diagonally opposite chelate rings are 13.08 (15) and 13.45 (11)°; each pair of rings is orientated in opposite directions. The bromo­thienyl rings are twisted out of the plane of the central N(4) core with dihedral angles in the range 51.7 (2)–74.65 (19)°. Supra­molecular chains along [001] are formed through C—H⋯Br inter­actions in the crystal packing. Three of the four bromo­thienyl units are disordered over two coplanar positions of opposite orientation with the major components being in 0.691 (3), 0.738 (3) and 0.929 (9) fractions.
