4-Nitro­phenyl α-l-rhamnopyran­oside hemihydrate

In the title compound, C(12)H(15)NO(7)·0.5H(2)O, there are two independent mol­ecules in the asymmetric unit, together with one water molecule. The pyran­oside rings each have close to a (1) C (4) chair conformation and the nitro groups are almost coplanar with the benzene rings. The water mol­ecule...

Sumario:In the title compound, C(12)H(15)NO(7)·0.5H(2)O, there are two independent mol­ecules in the asymmetric unit, together with one water molecule. The pyran­oside rings each have close to a (1) C (4) chair conformation and the nitro groups are almost coplanar with the benzene rings. The water mol­ecule links the two independent mol­ecules through O—H⋯O hydrogen bonds. All the hydroxyl groups are involved in hydrogen-bond inter­actions, giving rise to a three-dimensional network.
