Potential Precursor

Based upon the experimentally known but yet unexplained very different reactivities of the two isoelectronic and isolobal intermediates Pt(PMe3)2 and Pt(PEt3)2, the electronic structure and bonding capability of such 14 electron fragments as a function of their geometry (P-Pt-P angle α, determined by the phosphane cone angle) are investigated using molecular orbital calculations. A decrease of the P-Pt -P angle leads to an exceptionally pronounced energy ascent of the b2-HOMO of Pt(PR3)2 species, which, as a consequence, might lead to unusual reactivity patterns and bonding capabilities of 1,3-diphosphaplatinacyclobutane fragments, for which an extreme electronic situation is enforced by steric constraints. Dichloro[η2-bis(di-r-butylphosphino) methane]platinum(II), Pt(dtbpm)Cl2, is synthesized as a potential precursor of Pt(dtbpm), in order to allow experimental investigations of this taylor made four-membered ring chelate complex of Pt(0). The crystal and molecular structure of Pt(dtbpm)Cl2 · 2 CHCl3 has been determined by X-ray diffraction.

Abstract The crystal and molecular structure of [(C6H5)4P]2[Co(WS4)2] was determined from single crystal X-ray diffraction data (space group P21/c with a = 18.542(4), b = 15.443(2), c= 18.713(2) Å, β= 108.73(1)°, Z = 4). In the complex anion Co is coordinated by two bidentate chelating WS42- anions, with a nearly tetrahedral surrounding of Co. The bond lengths in the planar metal sulfur ring CoS2W are Co-S = 2.26 Å and W-S = 2.22 Å, while the terminal W-S bonds are 2.14 Å.
