p-Decylphenyl isocyanide and p-decylbenzonitrile: isomorphous isonitrile/nitrile isomers.
p-Decylphenyl isocyanide, p-C(10)H(21)-C(6)H(4)-NC or C(17)H(25)N, and p-decylbenzonitrile, p-C(10)H(21)-C(6)H(4)-CN or C(17)H(25)N, are isomorphous. The molecules lie in mirror planes, with the C(6) rings perpendicular to the mirror. The packing of both molecules includes an aliphatic region, with close to ideal packing of the C(10)H(21) chains, and an aromatic region, with phenyl ring-CN interactions. In addition, the CN ends of the molecules are also involved in a CN.NC dipolar interaction.
