چکیده
In the title compound, C(17)H(19)NO(8) [systematic name = dimethyl 4-hydroxy-4-methyl-2-(3-nitrophenyl)-6-oxocyclohexane-1,3-dicarboxylate], the cyclo-hexa-none ring exhibits a chair conformation. The meth-oxy-carbonyl groups are oriented in opposite directions with respect to the cyclo-hexa-none ring. In the crystal, O-H⋯O hydrogen bonds links the mol-ecules into chains running parallel to the a axis. These chains are connected by weak C-H⋯O hydrogen bonds, forming sheets parallel to the ab plane.
