Abstract The title compund C22H26N2O4,Mr=382.46 crystallizes in the orthorhombic space group P212121 with α=8.867(1)Å,b=13.228(2)Å,c=17.029(3)Å,V=1956.7(2)Å3,Z=4, Dcal=1.30 Mgm−3,F(000)=816, μ=6.89 cm−1, λ(CuKα)=1.5418 Å andT=298 K. The structure was solved by direct methods and refined by full-matrix least-squares. The finalR=0.046 for 1995 unique reflections. The phenyl rings are coplanar (oriented at an angle of 6.4(1)o) and orients at an angle of 112.2(1)o and 115.7(1)o, respectively with the piperazine ring. The piperazine ring adopts achair conformation and the substituents at the N-atoms are in an equatiorial position.
