Synthesis and Crystal Structure of Two Succinato‐Bridged Macrocyclic Nickel(II) Complexes

Abstract

Two dinuclear succinato-bridged nickel(II) complexes [Ni(RR-L)] 2 (μ-SA)(ClO 4 ) 2 (1) and [Ni(SS-L)] 2 (μ-SA)(ClO 4 ) 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 Ni II atoms display a distorted octahedral coordination arrangement, and the succinato ligand * Dr. G. C. Ou

Synthesis and crystal structures of three isophthalato-bridged macrocyclic nickel(II) complexes

“…The design and synthesis of extended bridged polymetallic complexes continue to be the focus of much attention owing to their potential applications in magneto-and materials chemistry. 1 -7 Many extended bridged dinuclear complexes such as μterephthalate, 8 -11 μ-oxalate, 12 -17 μ-N 3 , [18][19][20][21] μ-butene dicarboxylate 22 and μsuccinate 23 have been synthesized. In our previous report, 11 ,23 we used rigid terephthalic acid and flexible succinic acid ligand bridging macrocyclic nickel(II) complexes to construct one-dimensional hydrogen bonded helical chains.…”
