摘要：

The 42-electron cluster cation [pt3(μ3-CO)(μ-dppm)3]2+ (1) reacts with bidentate ligands LL = R2NCS2 to give [pt3(μ-CO)(μ-dppm)3(μ-R2NCS2)]+ (3a, R = Me; 3b, R = Et), with LL = R3PCS2 to give [pt3(μ-CO)(μ-dppm)3(M-R3PCS2)]2+ (3c, R = Et; 3d, R = cyclohexyl), and with LL = R2PCH2PR2 to give [pt3(μ-CO)(μ-dppm)3(μ-R2PCH2PR2)]2+ (3e, R = Me; 3f, R = Ph). Complex 3a has been shown by crystal structure analysis to contain the latitudinal Pt3(μ-dppm)3 core also present in 1. However, the carbonyl ligand has slipped from a symmetrical μ3-bonding mode found in 1 and now approximately doubly bridges the two platinum atoms that are also bridged by the dithiocarbamate ligand. The complexes 3a-d and 3f exhibit fluxionality of the added ligand LL, as shown by NMR spectroscopy. © 1990, American Chemical Society. All rights reserved.
