Pyridoxal (vitamin B-6 aldehyde) thiosemicarbazone (B6TSC) is deprotonated to its anion (B6TSC - H+) in basic solution at pH = 9. It shows an intense green fluorescence with lambda(max) = 500 nm and a quantum yield of unity. Zn(II)(B6TSC - H+)(acetate) displays an blue-green intraligand (B6TSC) fluorescence of moderate intensity. The complex cation [Pt(II)(B6TSC)Cl](+) is isolated as tetraphenylborate. In basic solution (pH = 9) this cation is deprotonated to the neutral complex [Pt(II)(B6TSC - H+)Cl] which exhibits the same green intraligand fluore-scence as the free anion (B6TSC - H+)(-). However, in the platinum complex this emission is much less intense. It is reduced to phi = 10(-2). (C) 2017 Elsevier B.V. All rights reserved.
