ResumoThe crystal and molecular structure of bis-2,2′,N,N′bipyridylamine copper(II) chloride tetra hydrate has been determined by three-dimensional X-ray analysis and refined by least-squares methods to conventional residuals of R = 0.081 and Rw = 0.096. The lattice parameters are a = 12.556(6), b = 28.002(7), c = 6.997(4) Å and β = 99.98(6)°. The space group is P21/a with four molecular units per unit cell. A total of 5049 unique data with ¦Fo¦ ⩾ 3σ{bditF} were used in the structure determination. The copper ion is pentacoordinate with a chloride ion and two pyridyl nitrogen atoms from different bipyridylamine ligands occpuying the equatorial positions of a distorted trigonal bipyramid. The remaining two pyridyl nitrogen atoms occupy the axial positions.
