Abstract

In the title compound, C(22)H(21)ClN(4)O(2)S, the bicyclic triazolopyrimidine ring system is nearly planar, and oriented at dihedral angles of 89.45 (3)° with respect to the chlorobenzene ring and 87.03 (3)° with respect to the terminal phenyl ring. In the crystal structure, mol-ecules are linked by π-π stacking inter-actions between the triazolopyrimidine rings [centroid-centroid distances of 3.88 (1) and 3.63 (1) Å].

摘要

在标题化合物C₂₂H₂₁ClN₄O₂S中,双环三唑并嘧啶环系近乎平面,相对于氯苯环的二面角为89.45 (3)°,相对于末端苯环的二面角为87.03 (3)°。在晶体结构中,分子通过三唑并嘧啶环之间的π-π堆积相互作用相连[质心-质心距离为3.88 (1) 和3.63 (1) Å]。
