Novel Concentration-Driven Structural Interconversion in Shape-Specific Solids Supported by the Octahedral [Re6(μ3-Se)8]2+ Cluster Core
dataset

cluster core, cis-[Re6(μ3-Se)8(PPh3)4(4,4‘-dipyridyl)2](SbF6)2 (1), is
used as a ditopic ligand with an enforced right angle between the
two 4,4‘-dipyridyl moieties for the coordination of Cd2+ ion. Two
coordination polymers, [{Re6(μ3-Se)8(PPh3)4(4,4‘-dipyridyl)2}2{Cd(NO3)2}](SbF6)4·21C4H10O·21CH2Cl2 (2) and [{Re6(μ3-Se)8(PPh3)4(4,4‘-dipyridyl)2}{Cd(NO3)3}](NO3)·2C4H10O·CH2Cl2 (3), are obtained. The relative concentration of Cd2+ determines which species
is isolated, and the conversion of the first structure into the second
is demonstrated experimentally.
