Abstract	Single crystals of 1-cyclohexylpiperazine-1,4-diium dichromate(VI), (C$_{10}$H$_{22}$N$_{2}$)[Cr$_{2}$O$_{7}$], were obtained by slow evaporation at room temperature from an aqueous solution of potassium dichromate, hydrochloric acid and 1-cyclohexylpiperazine. (C$_{10}$H$_{22}$N$_{2}$)[Cr$_{2}$O$_{7}$] is triclinic (P $$\bar 1$$ ) with a = 10.351(2) Å, b = 12.766(3) Å, c = 6.111(1) Å, α = 91.50(2)°, β = 104.26(3)°, γ = 94.91(2)°, V = 778.8(3) Å$^{3}$, and Z = 2. The structure determination performed from single crystal X-ray diffraction data leads to R $_{1}$/wR $_{2}$ reliability factors of 0.032/0.078. The asymmetric unit of the title salt C$_{10}$H$_{22}$N$_{2}$ $^{2+}$·Cr$_{2}$O$_{7}$ $^{2−}$, consists of one 1-cyclohexylpiperazine-1,4-diium dication and one dichromate dianion. These entities are linked together by N–H···O hydrogen bonds to form {(C$_{10}$H$_{22}$N$_{2}$)[Cr$_{2}$O$_{7}$]}$_{ n }$ infinite chains lying parallel to the (100) plane and running along the c axis. The intermolecular N–H···O hydrogen bonds link these chains into a two-dimensional network structure consolidated through C–H···O weak interactions.
