摘要:
Three new N,S-donor bidentate pyrazolyl-based ligands abbreviated as [PhNCSPz](-), 1, [PhNCSPz(Me2)](-), 2, and [PhNCSPz(Ph2)](-), 3, have been synthesized in THF by direct mixing of phenylisothiocyanide with suspension of appropriate sodium-pyrazolate salts and characterized by the common spectroscopic and analytical methods. The Cu(II) complexes of these anionic chelate ligands have been characterized and the crystal structure of Cu(PhNCSPz)(2), 4, has been determined. The space group of complex is P2(1)c, with a = 5.9313(3), b = 21.206(1) angstrom, c = 8.0667(4) angstrom, beta = 103.822(1)degrees. (c) 2005 Elsevier B.V. All rights reserved.
