Center-symmetric dimeric Re(CO)3+ complexes with Schiff base derivatives of salicylic aldehyde
摘要:
A simple synthetic procedure (reaction between Re(CO)(5)Cl and 2-[(E)-(phenylimino)methyl]- or 2-[(E)-(n-propylimino)-methyl]-phenol) leads to novel dimeric Re-2(CO)(6)(N boolean AND O-)(2) complexes with the structures confirmed by means of X-ray crystallography. The obtained species have been characterized by means of elemental analysis, FT-IR, UV-VIS absorption, and EI-MS spectroscopy. The solvolysis experiments performed in dimethylsulfoxide solutions point to well pronounced stability of the investigated species. (C) 2011 Elsevier B.V. All rights reserved.
