title: Diethyl 2,6-dihy-droxy-4-(3-nitro-phen-yl)-2,6-bis-(trifluoro-meth-yl)piperidine-3,5-dicarboxyl-ate.
abstract: In the title compound, C(19)H(20)F(6)N(2)O(8), the eth-oxy and ethyl groups are disordered over two sets of sites, with occupancy ratios of 0.212 (18):0.788 (18) and 0.746 (6):0.254 (6), respectively. The piperidine ring adopts a chair conformation. In the mol-ecule, intra-molecular O-H⋯O hydrogen bonds form two S(6) ring motifs. In the crystal, mol-ecules are linked via O-H⋯O and C-H⋯O hydrogen bonds, forming dimers.
