T. Yoshimura et al., Unusual capping chalcogenide dependence of the luminescence quantum yield of the hexarhenium(III) cyano complexes [Re-6(mu(3)-E)(8)(CN)(6)](4-), E2- = Se2- > S2- > Te2-, CHEM LETT, (10), 1999, pp. 1121-1122
Hexarhenium(III) clusters [Re-6(mu(3)-E)(8)(CN)(6)](4-) (E2- = S2-, Se2-, T
e2-) are luminescent at room temperature with the emission quantum yield an
d lifetime in the order E2- = Se2- > S2- >> Te2- both in acetonitrile and w
ater.
