Abstract
Single crystals of 1-cyclohexylpiperazine-1,4-diium dichromate(VI), (C10H22N2)[Cr2O7], were obtained by slow evaporation at room temperature from an aqueous solution of potassium dichromate, hydrochloric acid and 1-cyclohexylpiperazine. (C10H22N2)[Cr2O7] 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) Å3, 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 C10H22N2 2+·Cr2O7 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 {(C10H22N2)[Cr2O7]} 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.
