Binuclear zinc(II) complexes with the anti-inflammatory compounds salicylaldehyde semicarbazone and salicylaldehyde-4-chlorobenzoyl hydrazone (H2LASSBio-1064)
摘要:
Complexes [Zn-2(HL1)(2)(CH3COO)(2)] (1) and [Zn-2(L-2)(2)] (2) were synthesized with salicylaldehyde semicarbazone (H2L1) and salicylaldehyde-4-chlorobenzoyl hydrazone (H(2)LASSBio-1064, H2L2), respectively. The crystal structure of (1) was determined. Upon recrystallization of previously prepared [Zn-2(HL2)(2)(Cl)(2)] (3) in 1:9 DMSO:acetone crystals of [Zn-2(L-2)(2)(H2O)(2)]center dot[Zn-2(L-2)(2)(DMSO)(4)] (3a) were obtained. The crystal structure of 3a was also determined. All crystal structures revealed the presence of phenoxo-bridged binuclear zinc(II) complexes. (C) 2011 Elsevier Ltd. All rights reserved.
