Abstract
Three multinuclear complexes, [Co(L)(OAc)Co(CH3CH2OH)2]·H2O, [Zn(L)(OAc)Zn(CH3OH)], and [{Cd(L)(OAc)Cd(CH3OH)}2], containing a single-armed salamo-type bisoxime H3L have been synthesized and characterized structurally. The Co(II) complex forms a dimeric unit by intermolecular hydrogen bond interactions of neighboring dimeric molecules. The Zn(II) complex also forms a dimeric unit by intermolecular hydrogen bond interactions. Interesting features of the crystal structure include O⋯O short contacts. Meanwhile, self-assembling infinite 1-D, 2-D, and 3-D supramolecular structures are formed by intermolecular hydrogen bond and C–H⋯π interactions. The Cd(II) complex forms an infinite 2-D supramolecular structure by intermolecular hydrogen bond interactions. The photophysical properties of the Co(II), Zn(II), and Cd(II) complexes have also been discussed.
