|Abstract||ClPd(Î¼-dppm)2PtCl (1) reacts with (CNC6H4-2-OCH2-)2 to form a sparingly sol. and thermally stable orange polymeric material 4. 1 Reacts with 1 or 2 equiv. of CNC6H4-2-OCH3 to form the sol. A-frame d8-d8 model complexes 2 [ClPd(Î¼-dppm)2(Î¼-CNR)PtCl], and 3 [ClPd(Î¼-dppm)2(Î¼-CNR)Pt(CNR)](Cl) (R = C6H4-2-OCH3), resp. IR (Î½(NC) bridging vs. terminal) and NMR data reveal an A-frame structure where the terminal CNR ligands are bonded to Pt. 4 Which is amorphous (XRD) appears stable up to 290Â° (TGA), but exhibits an exothermic process between 215 and 255Â° upon the first scan in DSC, but disappears upon the second. Two compds., model 2 (Î»e = 674 nm; Ï„e = 0.38 Â± 0.01 Î¼s; Î¦e = 0.0079 (Â±10%)) and polymer 4 (Î»e = 660 nm; Ï„e = 0.18 Â± 0.01 Î¼s; Î¦e = 0.0056 (Â±10%)) are luminescent at 77K in the solid state and in fluid soln.
