biostudies-literatureUnknown68(Pt 10)Chen SThe title compound, C(44)H(30)N(4)O(2), was prepared from 6,6'-dibromo-2,2'-dieth-oxy-1,1'-binaphthalene through a coupling reaction with 4-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)benzaldehyde followed by a Knoevenagel reaction with malononitrile. The dihedral angle between the symmetry-related naphthalene ring systems is 68.82 (8)° while the dihedral angle between the the naphthalene ring system and the adjacent benzene ring is 16.92 (7)°. Four symmetry-independent mol-ecules which are linked by inter-molecular C-H⋯π inter-action generate the packing motif in the crystal structure. One of the CN groups is disordered over two sets of sites in a 0.60 (2):0.40 (2) ratio.Acta crystallographica.
