Scheme 3 Possible mechanism for cyanosilylation reaction in the
case of Ln(PDC) (Ln ¼ La, Pr and Sm) after activation.
The heterogeneous catalysis test was carried out for the Sm-
PDC catalyst. The Sm-PDC catalyst was isolated aer two 2
hours and the ltrate was allowed to stir for another 3 hours.
Only 4% additional conversion was found during the same time,
demonstrating the reaction was basically heterogeneous
(Fig. S4†). The recovered catalyst can be reused at least ve cycles
without loss of the activity (Fig. S5†). The PXRD pattern of the
Sm-PDC solid aer the h recycling reaction is similar to that
before the catalytic reaction, conrming that the maintenance of
the crystalline structure during the reaction processes (Fig. S6†).
Conclusions
In summary, we have developed three different types of
lanthanide-based coordination polymers based on pyridine-3,5-
dicarboxylate under solvothermal conditions. Compounds 1–3
show a 3D open network with cbu topology. Compounds 4 and 5
exhibit a (4,4)-grid layered structure with ABAB arrangement.
While compound 6 and 7 have a 1D zigzag chain. The structural
diversity of crystal structures may be ascribed to the effect of
lanthanide contraction. Moreover, the size-selective catalytic
activity towards cyanosilylation reaction was also discussed and
the catalysts can be readily recovered and repeatedly used.
