Abstract:
(2-Pyrrolylmethane)(2-pyrrolylmethyl)imine and an equimolar amount of 2-formylpyrrole give, in the presence of Ni(II) in hot MeOH, the novel tripyrrolic Ni(II) complex I. Planar I was characterized by x-ray crystallography [monoclinic C2/c; a = 21.461(1), b = 5.362(1), c = 22.0841(9) Å, b = 92.748(4)o, V = 2538.4(4) Å.3, Z = 8, R = 0.030, Rw = 0.024]. A mechanism for its formation is proposed, and its mass spectral behavior is discussed
