Synthesis and Crystal Structure of Two Succinato-Bridged Macrocyclic Nickel(II) Complexes
TLDR
Two dinuclear succinato-bridged nickel(II) complexes were synthesized and characterized by EA, Circular dichroism (CD), as well as IR and UV/Vis spectroscopy as discussed by the authors.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 spectroscopyread more
