title: 4-Nitro-phenyl α-l-rhamnopyran-oside hemihydrate.
abstract: The absolute configuration of the title compound, C(12)H(15)NO(7)·0.5H(2)O, was assigned from the synthesis. There are two rhamnoside mol-ecules and one water mol-ecule in the asymmetric unit, displaying O-H⋯O hydrogen bonding. One of the nitro groups does not conjugate efficiently with the benzene ring.
