A new tetraaza-macrocyclic complex involving a ten-membered chelate ring, trans-[Co(NO2)2(N410)]BF4(N410=1,4,7,10-tetraazacycloheptadecane) was prepared and the structure was determined by the X-ray diffraction method. The ten-membered chelate ring takes a distorted boat–chairboat form with the N–Co–N bite angle of 105.4(1)°.
制备了一种新的四氮杂-大环配合物,包括一个十元螯合环,反式-[Co(
NO2)2(N410)]BF4(N410=1,4,7,10-四氮杂环
十七烷),其结构由 X -射线衍射法。十元螯合环采用扭曲的船-椅船形式,N-Co-N 咬合角为 105.4(1)°。
