Abstract

The asymmetric unit of the title compound, C(10)H(10)N(2), contains one half-mol-ecule with the two shared C atoms lying on a twofold rotation axis. The 1,8-naphthyridine is almost planar with a dihedral angle of 0.42 (3)° between the fused pyridine rings. In the crystal, mol-ecules are linked into infinite chains along the c axis by inter-molecular C-H⋯N hydrogen bonds, generating R(2) (2)(8) ring motifs. In addition, the crystal structure is further stabilized by C-H⋯π inter-actions.

摘要

标题化合物C(10)H(10)N(2)的不对称单元包含半个分子，两个共享的C原子位于二重旋转轴上。1,8-萘啶几乎是平面的，稠合吡啶环之间的二面角为0.42 (3)°。在晶体中，分子通过分子间C-H⋯N氢键沿c轴连接成无限链，形成R(2) (2)(8)环 motif。此外，晶体结构通过C-H⋯π相互作用进一步稳定。
