- Abstract
Two dinuclear succinato-bridged nickel(II) complexes [Ni( RR-L)]2(μ-SA)(ClO4)2 ( 1) and [Ni( SS-L)]2(μ-SA)(ClO4)2 ( 2) (L = 5, 5, 7, 12, 12, 14-hexamethyl-1, 4, 8, 11-tetraazacyclotetradecane, SA = succinic acid) were synthesized and characterized by EA, Circular dichroism (CD), as well as IR and UV/Vis spectroscopy. Single crystal X-ray diffraction analyses revealed that the NiII atoms display a distorted octahedral coordination arrangement, and the succinato ligand bridges two central NiII atoms in a bis bidentate fashion to form dimers in 1 and 2. The monomers of {[Ni( RR-L)]2(μ-SA)}2 and {[Ni( SS-L)]2(μ-SA)}2 are connected by O-H ···O and N-H ···O hydrogen bonds into a 1D right-handed and left-handed helical chain along the b axis, respectively. The homochiral natures of 1 and 2 are confirmed by the results of CD spectroscopy.
