The synthesis of disilanyl platinum hydrides from the reaction of (dcpe)PtH$\sb2$ with disilanes is reported. The general reactivity pattern base upon the steric effects of the disilane is also reported for the reaction of (dcpe)PtH$\sb2$ with disilanes. It was found that the more hindering the substituents on the disilane are, the more strenuous the reaction condition become to yield disilanyl platinum hydride complexes. The x-ray crystal structure of (dcpe)Pt(H)(SiMe$\sb2$SiMe$\sb2$R) (R = o-(dimethylaminomethyl)phenyl) was obtained It was found that at elevated temperatures, disilanyl platinum hydride complexes are unstable to isomerization producing bis(silyl) complexes. No intermediates were observed when this isomerization was monitored by $\sp{31}$P NMR. The slow rate of isomerization allowed for the use of NMR to collect data for the calculation of the activation parameters. Kinetic isotope effects were also studied in this isomerization Several mechanistic possibilities may exist for this isomerization. The data collected for the isomerization will be compared with the expected result for each mechanistic possibility. Evidence was present as to which mechanism most closely can account for the observed Finally, the reaction of (Pd$\sb2(\mu$-dcpe)) with bis(thiophosphinyldisulfanes, R$\sb2$P(S)SSP(S)R$\sb2$ (R = Et, Ph), give the ionic complexes ((dcpe)Pd($\mu$-SPR$\sb2$S) $\sp{+}$ (SPR$\sb2$ S) $\sp{-}$ in good yields. The dimer ((Et$\sb2$PS$\sb2$)Pd($\mu$-Et$\sb2$PS$\sb2)\sb2$ was isolated in low yield. The x-ray crystal structure of a benzene solvate of ((dcpe)Pd(SP(Et$\sb2$)S) $\sp{+}$ (SP(Et)$\rm\sb2S\rbrack\sp-$ was obtained. Variable-temperature $\sp{31}$P NMR spectra of ((dcpe)Pd(SP(Et$\sb2$)S) $\sp{+}$ (SP(Et)$\sb2$S) $\sp{-}$ indicate a rapid interchange of the coordinated and free (SP(Et)$\sb2$S) $\sp{-}$ counterion in solution at room temperature
