【 摘 要 】

In the crystal of 2-(4-chloro­phen­yl)-N-(2-iodo­phen­yl)acetamide, C14H11ClINO, mol­ecules are linked by a combination of N—H⋯O and C—H⋯O hydrogen bonds to form a C(4)C(4)[R21(7)] chain of rings and chains of this type are linked by a combination of C—Cl⋯π(arene) and C—I⋯π(arene) inter­actions to form deeply puckered twofold inter­woven sheets. In the crystal of 2-(4-chloro­phen­yl)-N-(pyrazin-2-yl)acetamide, C12H10ClN3O, mol­ecules are linked into complex sheets by N—H⋯N, C—H⋯N and C—H⋯O hydrogen bonds, and by C—H⋯π(arene) inter­actions.
