Crystal structures of two C,N-disubstituted acetamides: 2-(4-chloro-phen-yl)-N-(2-iodo-phen-yl)acetamide and 2-(4-chloro-phen-yl)-N-(pyrazin-2-yl)acetamide.

ABSTRACT: In the crystal of 2-(4-chloro-phen-yl)-N-(2-iodo-phen-yl)acetamide, C₁₄H₁₁ClINO, mol-ecules 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) inter-actions to form deeply puckered twofold inter-woven sheets. In the crystal of 2-(4-chloro-phen-yl)-N-(pyrazin-2-yl)acetamide, C₁₂H₁₀ClN₃O, mol-ecules are linked into complex sheets by N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds, and by C-H⋯π(arene) inter-actions.
