| Abstract: | The reactions of stoichiometric amounts of Cu(CH3COO)2 · 2H2O or Ni(CH3COO)2 · 2H2O with KHL (potassium salt of salicylideneglycine) and 4,4′-bipy or 2,2′-bipy ethanol afforded Cu2(L)2(μ-4,4′-bipy)(4,4′-bipy)2] · 2H2O (1) (L = salicylideneglycine) and Ni(OAc)2(2,2′-bipy) (H2O)2 (2), respectively. The structure of 1 contains two Cu(II)'s, bridged by 4,4′-bipy; each copper is square pyramidal. Complex 2 contains a Ni(II) in highly distorted octahedral geometry. The two complexes were constructed into 3-D interwoven networks by typical H-bonding (i.e., O?H ··· O and N?H ··· O) and some other intra- or intermolecular weak interactions (i.e., C?H ··· O). |
