First example of pyrrole-2-carbaldehyde thiosemicarbazone as tridentate dianion in [Pd(η3-N4,N3,S-ptsc)(PPh3)] complex
摘要:
Reaction of pyrrole-2-carbaldehyde thiosemicarbazone (H(2)ptsc) with PdCl2(PPh3)(2) in 1: 1 mol ratio in presence of Et3N leads to complete dechlorination to generate square planar complex, [Pd(eta(3)-N-4, N-3,S-ptsc)(PPh3)] (1), existing as three independent molecules in the same unit cell, and H(2)Ptsc behaves in an unusual dinegative tridentate mode. Salicylaldehyde thiosemicarbazone (H(2)stsc) formed similar compound, [Pd(eta(3) -O,N-3,S-stsc)(PPh3)] (3). (c) 2007 Elsevier B.V. All rights reserved.
