摘要:
The reaction of the electronically unsaturated platina-beta-diketone [Pt(2){(COMe)(2)H}(2)(mu-Cl)(2)] (1a) with N boolean AND N donors led to the formation of diacetyl(hydrido) platinum(IV) complexes [Pt(COMe)(2)Cl(H)(N boolean AND N)] (2). By the reaction of these complexes with NaOH in a two-phase system (H(2)O/CH(2)Cl(2)) diacetylplatinum(II) complexes [Pt(COMe)(2)(N boolean AND N)] (N boolean AND N = bpy, 4a; 4,4'-Me(2)-bpy, 4b; 4,4'-t-Bu(2)-bpy, 4c; 4,4'-Ph(2)-bpy, 4d; 4,4'-t-Bu(2)-6-n-Bu-bpy, 4e; bpym, 4f; bpyr, 4g; phen, 4h; 4-Me-phen, 4i; 5-Me-phen, 4j) were obtained. All complexes were characterized by microanalysis, IR and (1)H and (13)C NMR spectroscopy. Additionally, complexes 4a, 4c, 4d and 4e were characterized by single-crystal X-ray diffraction analysis. The observed variety of packing patterns resulting from pi-pi stacking and hydrogen bonding is discussed. (C) 2008 Elsevier B.V. All rights reserved.
