Abstract
Bis(iminodiacetamide)copper(II) perchlorate was newly synthesized, and the crystal structure was determined from three-dimensional X-ray data collected on a diffractometer. The structure was refined by blockdiagonal least-squares methods to give R=0.08 for the 950 observed reflections. The crystals are monoclinic with the space group of P21/c. There are two formula units per unit cell with a=6.183, b=17.617, c=8.900 A, and β=110.2°. The complex is centrosymmetric, in which the two ligand molecules coordinate to the central copper atom through two imino nitrogen atoms and two of the four amide oxygen atoms in trans positions, exhibiting a square-planar coordination. The other two amide oxygen atoms are weakly bonded to the copper atom above and below this square-plane, thus completing an s-facial distorted (elongated) octahedral coordination. The complex cations are held together through hydrogen bonds to form infinite chains along the a axis. These chains are connected with one another by perchlorate ions...
