    Description / Table of Contents: Penicillamine Complexes of Nickel, Chromium, and Molybdenum  -  Structural Particularity and Biological/Medical RelevanceThe compounds Tl2[NiII(H2O)6][NiII(D-pen)(L-pen)]2[NiII(SCN)2(H2O)4] 1, Tl[NiII(D-pen)2H] · H2O 2, Tl[CrIII(D-pen)2] 3, and Na2[Mo2VO4(pen)2] · 3 CH3OH · 3 H2O 4 have been prepared by the reaction of nickel nitrate (for 1), nickel acetate (for 2), potassium chromate (for 3), and sodium molybdate (for 4) with D- and D, L-penicillamine, respectively. They were characterized by single-crystal X-ray structure analysis and other physical methods. Whereas penicillamine acts as a bidentate (N, S)-ligand in 1 and 2, CrIII (in 3), and MoV (in 4) are coordinated to the three ligand atoms N, O, and S. The presence of three different types of NiII-complexes a cationic, a neutral, and an anionic one in 1 is remarkable.For crystal data see Inhaltsübersicht.
    Notes: Die Verbindungen Tl2[NiII(H2O)6][NiII(D-Pen)(L-Pen)]2[NiII(SCN)2(H2O)4] 1, Tl[NiII(D-Pen)2H] · H2O 2, Tl[CrIII(D-Pen)2] 3 und Na2[Mo2VO4(Pen)2] · 3 CH3OH · 3 H2O 4 wurden durch Umsetzung von Nickelnitrat (für 1), Nickelacetat (für 2), Kaliumchromat (für 3) und Natriummolybdat (für 4) mit D- bzw. D, L-Penicillamin in wäßriger Lösung dargestellt und durch Einkristallstrukturanalyse und andere physikalische Methoden charakterisiert. Während in den Ni-Pen-Komplexen von 1 und 2 Penicillamin als zweizähniger Ligand (N, S) fungiert, sind CrIII in 3 und MoV in 4 über N, O und S koordiniert. Bemerkenswert ist, daß in 1 drei verschiedene Ni-Komplexe und zwar ein kationischer, ein neutraler und ein anionischer in einer Elementarzelle vorliegen.1: C2/m, a = 1 484,6(4), b = 1 358,7(4), c = 1 204,7(3) pm, β = 103,75(2)°, V = 2 360,4(11) ° 106 pm3, R = 0,042 für 1 633 unabhängige Reflexe (Fo〉 4,0σ(Fo)), Z = 2.2: C2, a = 2 279,9(7), b = 613,1(1), c = 1 275,2(3) pm, β = 110,94(2)°, V = 1 664,8(6) · 106 pm3, R = 0,056 für 1 413 unabhängige Reflexe (Fo〉 4,0σ(Fo)), Z = 4.3: C2, a = 2 054,0(3), b = 592,1(1), c = 606,7(1) pm, β = 92,89(1)°, V = 736,95(17) · 106 pm3, R = 0,028 für 862 unabhängige Reflexe (Fo〉 4,0σ(Fo)), Z = 2.4: P1, a = 996,2(4), b = 1 222,2(7), c = 1 395,3(7) pm, = 114,27(4), β = 104,55(4), γ = 95,63(4)°, V = 1 459,4(13) · 106 pm3, R = 0,072 für 3 763 unabhängige Reflexe (Fo〉 4,0σ(Fo)), Z = 2.
