Synthesis of 2- (2, 4-dimethyl pyrrolyl) benzothiazole by chemical means and molecular structure by X-ray crystallographic techniques is reported. The compound crystallizes in the orthorhombic crystal system with space group Pbca and unit cell parameters: a = 12.161(9), b = 0.787(1), c = 16.792(2) Ǻ, V = 2202.8(4) Ǻ3 and Z = 8. The final reliability index is 0.073 for 7,959 observed reflections. The benzothiazole and pyrrole rings exist in planar conformations. The dihedral angle between the least-squares planes of both these moieties is 13.31°. There exists an isolated C4–H4···N1 intermolecular interaction, besides two C–H···S and C–H···N intermolecular interactions. The presence of C–H···S and C–H···N intramolecular interactions make the present molecule look like a virtual two-six-membered and three-five-membered ring structure.

othiazole和吡咯环呈平面构象。两个部分的最小二乘平面之间的二面角为13.31°。除了两个C-H·S和C-H·N分子间相互作用外,还存在一个孤立的C4-H4·N1分子间相互作用。C-H·S和C-H·N分子内相互作用的存在使该分子看起来像一个虚拟的二六元和三五元环结构。通过化学手段合成2-(2,4-二甲基吡咯基)苯并噻唑,并通过X射线晶体学技术报告分子结构。该化合物在正交晶系中结晶,空间群为Pbca,晶胞参数为:a=12.161(9),b=0.787(1),c=16.792(2)Ǻ,V=2202.8(4)Ǻ3,Z=8。7959个观察到的反射的最终可靠性指数为0.073。苯并噻唑和吡咯环呈平面构象。两个部分的最小二乘平面之间的二面角为13.31°。除了两个C-H·S和C-H·N分子间相互作用外,还存在一个孤立的C4-H4·N1分子间相互作用。C-H·
