Abstract

Benzyl 4-chloro-3-nitro­benzoate, C₁₄H₁₀ClNO₄, crystallizes with Z‘ = 2 in the space group P. The mol­ecules are linked by three independent C-HO hydrogen bonds into chains of edge-fused R₄⁴(26) and R₄⁴(34) rings, and these chains are linked into a three-dimensional framework structure by aromatic – stacking inter­actions. In benzyl 4-nitro­benzoate, C₁₄H₁₁NO₄, the mol­ecules are linked by two independent C-HO hydrogen bonds into chains containing two types of R₂²(10) ring.
