“…Major reasons for this interest stem from the d 10 metal ions not only possessing various coordination numbers and geometries, but also exhibiting photoluminescent properties when bound to functional ligands. Organic aromatic multicarboxylate, such as 1,n-benzenedicarboxylate (n =2,3,or4), 1,2,3-benzenetricarboxylate, and 1,2,4,5-benzenetetracarboxylate, as the linkers between the metal centers, present versatile coordination modes, can yield predetermined networks and have been widely utilized to construct coordination polymers [8][9][10][11][12]. 5-methylisophthalic acid (H 2 mip), aderivative of isophthalic acid, has asubstituent, asubtle difference to H 2 ip, and the difference mays ignificantly influence the resulting metal-organic frameworks, although substituents will not be involved in metal coordination.…”
