  Influence of steric and electronic factors in the stabilization of five-coordinate ethylene complexes of platinum(II): X-ray crystal structure of [PtCl2(2,9-dimethyl-1,10-phenanthroline-5,6-dione)]

  摘要：

  Reactions of Zeise's salt (K[Pt(eta(2)-C2H4)Cl-3]) with oxidized phenanthroline ligands (1, 10-phenanthroline-5,6-dione, phedon, and 2,9-dimethyl-1,10-phenanthroline-5,6-dione, Me(2)phedon) are reported. Comparison with analogous reactions involving unoxidized phen (1,10-phenanthroline) and Me phen (2,9-dimethyl-1,10-phenanthroline) ligands indicates that these latter ligands are less capable to stabilize the five-coordinate species [PtCl2 (eta(2)-C2H4)(phenanthroline)] in which the phenanthroline and the olefin share the trigonal plane and two chlorines are in the axial positions. The X-ray structure of the four-coordinate species [PtCl)(Me(2)phedon)] indicates that the major difference between oxidized and unoxidized phenanthrolines is the loss of aromaticity of the central ring of phenanthroline. As a consequence, the oxidized phenanthroline becomes more flexible and can undergo a bowlike distortion so to reduce steric interaction between ortho substituents of phenanthroline and cis chlorine ligands. The increase in stability of the four-coordinate species with Me(2)phedon is concomitant with an increase in stability of the five-coordinate precursor complex with ethylene. In the latter case the stabilization is not of sterical origin but stems from reduced electron-donor properties of oxidized phenanthrolines. The balance of the two effects is such that the equilibrium between five- and four-coordinate species is more shifted in favour of the former species in the case of Me2phedon than in the case of Me(2)phen.

  progressively restore the Pt(II) oxidation state by transferring the electron to the peripheral organic ligand. The latter process can involve multiple electron additions in the macroelectrolysis time scale. The related platinum(IV) complexes [PtX(4)(L)] undergo irreversible two-electron reduction accompanied by fast release of the axial ligands and formation of the corresponding platinum(II) species.

  coordinated halido ligands’ ionic radii was discovered in Pt(II) and Pt(IV) complexes. The reduction of 195Pt NMR frequencies parallels the increase of coordinated halido ligands’ ionic radii sum. This suggests that each halido ligand may act as a conducting ring whose induced electric current shields the 195Pt NMR signals proportionally to the ionic radius of the coordinated halido ligand.

  在Pt（II）和Pt（IV）配合物中发现了实验观察到的195个Pt NMR信号与配位卤代配体的离子半径的总和之间的反线性关系。195 Pt NMR频率的降低与配位卤代配体的离子半径总和的增加平行。这表明每个卤代配体都可以充当导电环，其感应电流与配位卤代配体的离子半径成比例地屏蔽195 Pt NMR信号。

  Abstract Different types of products can be obtained by addition of protic acids HX (X=Cl, BF 4 ) to Pt(O) species of general formula [Pt(ol)(N-N)] (ol=olefin; N-N=N,N-chelate) according to the features of the two coordinated ligands. The typical attainment of four-coordinate hydrocarbyl derivatives by insertion of the alkene into the Pt-H bond is compared with the recently reported isolation of stable
