Crystal Structures of Two Substituted Pyridinecarboxylates

Two substituted pyridinecarboxylates were synthesized; Ethyl 2-bromo-
4-(4-chlorophenyl)-6- phenyl-3-pyridinecarboxylate, C20H15BrClNO2 (1) and
Ethyle 4-(4-chlorphenyle)-6-phenyle-2- (1-piperdinyle)-3-pyridinecarboxylate,
C24H23ClN2O3 (2). It was found, that compound 1 belongs to the orthorhombic
system with space group P212121 and compound 2 to the triclinic system with
space group P 1 . The piperidine ring in 2 has the shape of the distorted chair
configuration. The crystal data of the two compounds and their atomic
coordinates with the equivalent isotropic displacement parameters are presented.
