Crystal structure and Hirshfeld surface analysis of ethyl (3E)-5-(4-chlorophenyl)-3-{[(4-chlorophenyl) formamido]imino}-7-methyl-2H,3H,5H-[1,3]thiazolo[3,2-a]pyrimidine-6-carboxylate.

In the title mol­ecule, C₂₃H₂₀C_l2N₄O₃S, the thia­zole ring is planar while the pyrimidine unit fused to it adopts a screw-boat conformation. In the crystal, thick sheets parallel to the bc plane are formed by N--H⋯N, C--H⋯N and C--H⋯O hydrogen bonds together with π-π inter­actions between the formamido carbonyl groups and the thia­zole rings. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (30.9%), Cl⋯H/H⋯Cl (20.7%), C⋯H/H⋯C (16.8%) and O⋯H/H⋯O (11.4%) inter­actions.
