摘要：
A complex containing the face-capped octahedral [Re-6(mu(3)-Se)(8)](2+) cluster core, cis-[Re-6(mu(3)-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, [{Re-6(mu(3)-Se)(8)(PPh3)(4)(4,4'-dipyridyl)(2)}(2){Cd(NO3)(2)}](SbF6)(4).21C(4)H(10)O.21CH(2)Cl(2) (2) and [{Re-6(mu(3)-Se)(8)(PPh3)(4)(4,4'-dipyridyl)(2)}{Cd(NO3)(3)}](NO3).2C(4)H(10)O.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.
