The crystal structure of the title complex salt has been determined by single-crystal X-ray structure analysis.The crystal data are as follows;Monoclinic,P2_1/c,a=15.6480 (10)Å,b=16.7870 (10)Å,c=10.347 (2)Å,β=90.790 (10),V=2717.7 (6)Å³,Z=3,and R=0.0333 for 4789 unique reflections.The complex anion has a pseudo-octahedral structure distorted more than the Cr^Ⅲ and Co^Ⅲ analogs,in which cach iminodiacetato ligand (ida^2-) is coordinated in a facial fashion with the two N atoms in a cis configuration,resulting in an unsym-fac structure.
