[meso-5,10,15,20-Tetra­kis(5-bromo­thio­phen-2-yl)porphyrinato-κ⁴N,N′,N′′,N′′′]nickel(II)

The Ni^II atom in the title porphyrin complex, [Ni(C₃₆H₁₆Br₄N₄S₄)], 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 N₄ 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 N₄ 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.

(E)-1-(2,4-Dimethyl­quinolin-3-yl)-3-(4-methyl­phen­yl)prop-2-en-1-one

In the title compound, C₂₁H₁₉NO, there are two mol­ecules in the asymmetric unit (Z′ = 2). There are π–π inter­actions between these two mol­ecules [centroid–centroid distance = 3.678 (2) Å], as well as a weak C—H...O inter­action. The conformation adopted by the two mol­ecules is such that the quinoline mean plane and the benzene ring are almost perpendicular [89.04 (5) and 76.89 (4)°]. In each mol­ecule, the methyl group of the tolyl ring is disordered over two conformations, with occupancy ratios of 0.56 (3):0.44 (3) and 0.65 (3):0.35 (3).
