摘要
X-Ray analysis of trans-1,2-bis{meso-[nickel(II)octaethylporphyrinyl]}ethene has revealed that the compound has nonplanar structure and the nickel-coordination planes of porphyrin rings are close to perpendicular (72.5-degrees) to the plane of the central double bond. Both porphyrin rings have saddle-shaped structure due to the steric repulsion between ethyl substituents.
