Conformational control of ligands to create a finite metal–organic cluster and an extended metal–organic framework†
Abstract
While a twofold interpenetrated 3-D metal–organic framework, [Cu3(L1)2(H2O)3]·14DMF·16H2O (1) (where, L1 is 4,4′,4′′-[1,3,5-benzenetriyltris(carbonylimino)]trisbenzoate and DMF is N,N′-dimethylformamide), with a (3,4)-connected pto net topology was prepared using a tricarboxylic acid linked via secondary
