The molecules of N-(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)-2-chloro-N-(4-methoxybenzyl) acetamide, C(23)H(26)ClN(3)O(2), are linked into a chain of edge-fused centrosymmetric rings by a combination of one C-H center dot center dot center dot O hydrogen bond and one C-H center dot center dot center dot pi (arene) hydrogen bond. In N-(3-tert-butyl1-phenyl-1H-pyrazol-5-yl)-2-chloro-N-(4-chlorobenzyl) acetamide, C(22)H(23)Cl(2)N(3)O, a combination of one C-H center dot center dot center dot O hydrogen bond and two C-H center dot center dot center dot pi (arene) hydrogen bonds, which utilize different aryl rings as the acceptors, link the molecules into sheets. The molecules of S-[N-(3-tert-butyl-1phenyl-1H-pyrazol-5-yl)-N-(4-methylbenzyl) carbamoyl] methyl O-ethyl carbonodithioate, C(26)H(31)N(3)O(2)S(2), are also linked into sheets, now by a combination of two C-H center dot center dot center dot O hydrogen bonds, both of which utilize the amide O atom as the acceptor, and two C-H center dot center dot center dot pi (arene) hydrogen bonds, which utilize different aryl groups as the acceptors.
