Various amino-carboxylate coordination polymers were synthesized by the reaction between the divalent metal ion and flexible primary linker of bis(4-carboxy-benzyl)amine (BCBA) and secondary N-colinkers where the addition of secondary N-colinkers assist in structural assemble and 'structural reroll' to diversify the outcome coordination polymers product. The project is explored as 2 folds (i) multiple polymorphic phases of Cu2+, (ii) toward making porous coordination polymers with N-colinkers. To this end, it was observed that there are multiple polymorphic phases from the solvothermal reaction of Cu(NO3)2 and BCBA in DMF:H2O, particularly ones with channel that the solvents reside in. Upon using pyrazine for the reaction of M(NO3)2 and BCBA where M = Co, Ni, Cu gave the structure of M3(BCBA)2(BCBA-H)2(pyz)(H2O)2 features trinuclear cluster with 1D empty channel running through, whereas in the case of Cu gave the structure of Cu2(BCBA-H)4(pyz) featured dinuclear cluster paddlewheel of Cu2+ bridged by the pyrazine secondary linker. Interestingly, thje case of Zn2+ with longer N-colinkers gave the structures of 3D interpenetrated network, and upon changing the solvent from DMF to DBF created a 2D porous structure of Zn2(BCBA-H)2(4,4’-bipy)(H2O)2(NO3)2, whereas less bulkier solvent of dimethylformamide createsdinterpenetrated network of Zn(BCBA-H)2(4,4’-bipy)(H2O), which suggested the DBF acted as a bulky template assembling the structures together and blocking the interpenetration. Unusually, adding acetic acid instead in DMSO:DBF created the structure of [Zn2(BCBA-H)2(CH3COO)](NO3)·DBF·DMSO where it formed a paddlewheel Zn2+ cluster that are bridged together by the acetic acid linker instead. These structures reported herein have accessible, porous channel for separation of important resources.
