ABSTRACT: The title compound, C40H46N2 {systematic name: 12,30-di-aza-hepta-cyclo[21.13.1.1(5,19).1(6,18).1(10,14).1(24,36).1(28,32)]do-tetra-conta-1(37),5(40),6(41),10(42),11,13,18,23,28,30,32(39),36(38)-dodeca-ene}, has syn-anti-syn geometry wherein the two outer [3.3]meta-cyclo-phane (MCP) moieties have a syn geometry, and contain the facing benzene and pyridine rings at dihedral angles of 26.26 (10) and 26.46 (10)°, respectively. The rings of the central [3.3]MCP unit are not parallel, but orientated at a slight angle of 2.66 (9)°. Three bridging methyl-ene groups are disordered over two sets of sites in a 0.60:0.40 ratio. In the crystal, the mol-ecules are linked by C-H⋯N inter-actions and inter-molecular C-H⋯π short contacts, generating a three-dimensional network.
