Abstract: | A complex of copper(II) with the diethylenetriaminemonopripionate ligand Cu2(4-Dtmp)2](ClO4)2 (I) is synthesized and characterized using X-ray diffraction. The crystals of compound I are monoclinic, a = 7.740(2) Å, b = 19.199(3) Å, c = 8.449(2) Å, β = 91.61(2)°, Z = 2, and space group P21/n. The structural units of crystal I are centrosymmetric dimeric cations and statistically disordered ClO
4
−
anions. In the cation, the copper atom is coordinated by three N atoms mean Cu-N, 2.01(1) Å] and two O atoms Cu-O, 2.134(6)
Å and 1.958(7) Å] of the pentadentate bridging-chelate Dtmp ligand, which occupy vertices of the trigonal bipyramid. The binuclear cations are linked via centrosymmetric pairs of hydrogen
bonds into ribbons aligned parallel to the a axis of the crystal. The ClO
4
−
anions form columns in the same direction. In the crystal, the cationic ribbons and anionic columns alternate in a chessboard
fashion.
