摘要：
Brown block-shaped crystals of bis{2-methoxy-6-[(2-diethylaminoethylimino)methyl]phenolato}thiocyanatocobalt(III) perchlorate, the first cobalt(III) complex derived from the Schiff base ligand HL, [CoIII(L)(HL)(NCS)].ClO4 (HL=2-methoxy-6-[(2-diethylaminoethylimino)methyl]phenol) have been obtained and characterized by elemental analysis and X-ray single crystal determination. The complex crystallizes in the monoclinic space group P21/c with unit cell dimensions a=16.087(3) Å, b=12.354(3) Å, c=16.762(3) Å, β=93.77(3)°, V=3324.1(12) Å3, Z=4, R1=0.0741 and wR2=0.1366. X-ray structure determination revealed that the complex consists of a [CoIII(L)(HL)(NCS)]+ cation and a disordered perchlorate anion. The Co atom in the cation is six-coordinate in an octahedral coordination. In the crystal structure, the perchlorate anions are linked to the cations through intermolecular C–H⋯O hydrogen bonds, forming zigzag chains running along the caxis. It is the first cobalt(III) complex derived from the Schiff base ligand HL.
