摘要

The synthesis and crystal structures of two new salts of chromium(III) with pyridine-2,6-dicarboxylic acid H_2Pda (and 2,2′-bipyridyl, Bpy, as a co-ligand) are reported, (HPyz)[Cr(Pda)_2](H_2Pda)- (H_2O)_5 (1) and [Cr(Pda)(Bpy)(H_2O)][Cr(Pda) _2](H_2O)_2 (2). Both crystal structures contain the octahedral [Cr(Pda)_2]? anion with the pincer-type O,N,O-Pda ~(2?) ligand. In1, the pyrazole additive does not act as a ligand, rather it is included as a mono-protonated cation. In 2, both Pda~(2?), the neutral 2,2′-bipyridyl and water are coordinating Cr~(3+) in the cation [Cr(Pda)(Bpy)(H_2O)]+.
