Abstract
The reaction of an arm-non-equivalent tripodal ligand pyridin-4-ylmethyl-3,5-bis-(pyridin- 4-ylmethoxy)benzoate (pbb) with Zn(NO3)2 and Co(SCN)2 affords two 2D coordination polymers {[Zn(pbb)(NO3)2]·(H2O)·(DMF)}n (1) and {[Co(pbba)2 (SCN)2]·(DMF)}n (2) (pbba = methyl-3,5-bis(pyridin-4-ylme- thoxy)benzoate). In 1, pbb performs as a three-connector to bridge Zn(NO3)2 into a 2D brick-wall-like structure. Ligand pbba, originated from pbb in the self-assembly process of 2 under hydrothermal condition, performs as a two connector to bridge Co(SCN)2 into (4,4) sheet with 2D→2D interpenetration.
