The title compounds, CHNO and CHClNO, are heterocyclic 1,3,4-oxa-diazole derivatives which differ from each other in the groups attached to the carbon atoms: a meth-oxy-phenyl ring and a benzo-nitrile group in (I) and a chloro-phenyl ring and an acetamide group in (II). Short intra-molecular C-H⋯O hydrogen bonds occur in both mol-ecules. The crystal structure of (I) features C-H⋯N hydrogen bonds, while in the crystal structure of (II), N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds are observed.
标题化合物CHNO和CHClNO是杂环1,3,4-恶二唑衍生物，它们在连接到碳原子的基团上彼此不同：（I）中的甲氧基苯基环和苯腈基团，以及（II）中的氯苯基环和乙酰胺基团。两种分子中均存在短程分子内C-H⋯O氢键。（I）的晶体结构具有C-H⋯N氢键，而在（II）的晶体结构中，观察到N-H⋯N、C-H⋯N和C-H⋯O氢键。
