  Preparation, crystal structure and kinetics of acid hydrolysis of an isomer of [Cr(picdien)Cl][ZnCl₄][picdien = 1,9-bis(2′-pyridyl)-2,5,8-triazanonane]

  摘要：

  The complex [Cr(picdien)Cl][ZnCl4] [picdien = 1,9-bis(2'-pyridyl)-2,5,8-triazanonane] has been prepared and its structure determined by a single-crystal X-ray diffraction study of the triclinic crystals: a = 9.118(3), b = 9.581(5), c = 14.042(5) angstrom, alpha = 78.04(3), beta = 86.37(3)-degrees, and gamma = 76.56(3)-degrees. The complex cation has the anti-alpha-beta configuration. The kinetics of aquation of the perchlorate salt has been studied in dilute aqueous nitric acid solution, [complex] = 5 x 10-3 mol dm-3. The rate constants are independent of [H+] over the range 0.10 < [H+] < 0.001 mol dm-3: K25-degrees-c = 6.0 x 10-6 S-1, delta +/+ = 93.1 +/- 2.2 kJ mol-1, DELTA-S +/+ = -32.9 +/- 6.9 J K-1 mol-1.
