(1,3-Diamino-2-propanol-N,N')diiodoplatinum(II) and (1,3-diamino-2-propanol-N,N')dichloroplatinum(II)

Bis(1,3-diaminopropane)diiodoplatinum(IV) Diiodide Dihydrate

“…The high residual electron density of 1.013 e ~-3 lies ca 1.71 from the Pt ion. A similar but much higher maximum has been reported earlier for platinum compounds (Mtgnamisi-Btlomb6 & Endres, 1985;Oksanen et al, 1991).…”

“…A greenish precipitate contaminated with black particles formed rapidly. A similar greenish crude product with black particles was obtained in a previous synthesis with 1,3-diamino-2-propanol (Oksanen et al, 1991).…”

“…The reaction of K2PtI4, prepared by this path, with amines thus easily yields a mixture of products. The title compound, (I), was obtained during an investigation of the nature of a black contaminant found in the crude product of an earlier synthesis (Oksanen, Kivek~is, Lumme & Laitalainen, 1991). The formation of black by-products has also occasionally been mentioned in the literature for the reactions of K2PtCI4 or K[PtC13NH3] with amines or pyridine derivatives (Connors et al, 1972;Kong & Rochon, 1978;Hydes, 1982).…”

(1,3-Diaminopropan-2-ol-κ2N,N′)(3-hydroxycyclobutane-1,1-dicarboxylato-κ2O,O′)platinum(II) monohydrate

“…The square plane is constituted by the 2-hydroxy-1,3-diaminopropane molecule which acts as a tetradentate ligand through its 2hydroxy-1,3-diaminopropane N atoms and 1,1-cyclobutanedicarboxylate O atoms. The 2-hydroxy-1,3-diaminopropane ligand has already been used in the dichloroplatinum complex (Oksanen et al, 1991). The 1,1-cyclobutanedicarboxylate ligand displays a similar geometry to those described in the literature (Tu et al, 2004;Zhang et al, 2002;Ali et al, 2002).…”
