Abstract:

In the crystal structures of the title com-pounds, namely μ-aqua-κ2 O:O-di-μ-di-phenyl-acetato-κ4 O:O'-bis-[(di-phenyl-acetato-κO)bis-(pyridine-κN)nickel(II)], [Ni2(C14H11O2)4(C5H5N)4(H2O)] (1) and μ-aqua-κ2 O:O-di-μ-di-phenyl-acetato-κ4 O:O'-bis-[(2,2'-bi-pyridine-κ2 N,N')(di-phenyl-acetato-κO)nickel(II)]-aceto-nitrile-di-phenyl-acetic acid (1/2.5/1), [Ni2(C14H11O2)4(C10H8N2)2(H2O)]·2.5CH3CN·C14H12O2 (2), the com-plex units are stabilized by a variety of intra- and inter-molecular hydrogen bonds, as well as C-H⋯π and π-π contacts between the aromatic systems of the pyridine, dipyridyl and di-phenyl-acetate ligands. Despite the fact that the di-phenyl-acetate ligand is sterically bulky, this does not inter-fere with the formation of the described aqua-bridged dimeric core, even with a 2,2'-bi-pyridine ligand, which has a strong chelating effect.
