AI Technical Summary

Problems solved by technology

[0003] In terms of the metal selection of magnetic complexes, although the use of transition metals, rare earths or coordination polymers mixed with rare earths and transition metals has been widely reported, there are few reports on the series of magnetic complexes based on the linear arrangement between metals. In terms of heterometals composed of transition metals, most of them are concentrated in Ln-Cu, Ln-Mn systems, and most of Ln(III) are Gd(III) ions

At present, the heterometallic coordination polymer based on zero-dimensional linear pentanuclear Ln-Co has not been reported so far.
