 Title    Synthesis, Solution, Molecular and Crystal Structure of Bis[5-(coproporphyrinato-I tetraethylester)nickel(II)]l,2-ethane  
 Abstract    Vilsmeier formylation of the oporphyrin-I tetraethyl ester Ni-complex (III) followed by reduction of the intermediary imine salt (IV) with N aBH4 gave the o-dimethylaminomethyl-coproporphyrin-I Ni-complex (V). Heating the latter in methyl iodide gave 65% of the eth­ ane-bis-porphyrin (I), which has been characterized by NMR-spectroscopy and a molecular and crystal structure investigation. The crystal structure shows an extended structure of the bisporphyrin with a parallel arrangem ent of the porphyrin subunits. Crystal data: I -C90H 106N8Ni2O 16.
