Isolated Co15 clusters and their assembly into a 3D network: conformation-directed synthesis.
Isolated clusters of 15 Co atoms interconnected by six organic linkers, each with two carboxylic and one phosphonic groups, N(CH(2)COO(-))(2)(CH(2)PO(3)(2-)), are synthesized with deprotonated trans-cyclohexanehexacarboxylic acid, C(6)H(6)(COO(-))(6), as counteranions. The cis conformation of the latter, on the other hand, coordinates to the same clusters by replacing the terminal water ligands and links them into a 3D network.
