N-(3-tert-Butyl-1-phenyl-1H-pyrazol-5-yl)-N-(4-methoxybenzyl)acetamide: a hydrogen-bonded chain of centrosymmetric rings

Hydrogen-bonding patterns in three substituted N-benzyl-N-(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)acetamides

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...O hydrogen bond and one C-H...pi(arene) hydrogen bond. In N-(3-tert-butyl-1-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...O hydrogen bond and two C-H...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-1-phenyl-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...O hydrogen bonds, both of which utilize the amide O atom as the acceptor, and two C-H...pi(arene) hydrogen bonds, which utilize different aryl groups as the acceptors.
