Abstract:
The crystal and molecular structure of a clip containing molecule is described. The structure was solved by vector search methods and refined by least squares methods to R(1) = 0.0768 [I > 2 sigma(I)]. Crystal data: C40H30N4O2 . HCCl3, triclinic, space group P (1) over bar, a = 9.302(2), b = 12.981(2), c = 15.765(2)Angstrom, alpha = 65.91(2)degrees, beta = 76.40(2)degrees, gamma = 80.15(1)degrees, V = 1682.9(4)Angstrom(3), Z = 2.
