✦ Synopsis
Professor Dieter Fenske zum 60. Geburtstag gewidmet Inhaltsübersicht. 1,2-Dithiooxalat-und 1,2-Dithioquadratationen haben je ein Paar harter und weicher Donoratome und können damit koordinationspolymere Verbindungen bilden. Über die Strukturen vier solcher Verbindungen wird berichtet: In [BaCr 2 -(bipy) 2 (1,2-dtox) 4 (H 2 O) 2 ] sind zehnfach von Sauerstoffatomen koordinierte Bariumionen über Paare von Cr(bipy)(1,2-dtox) 2 -Einheiten kettenförmig verbunden. [Ni(cyclam)(1,2-dtsq)]•2DMF hat ebenfalls eine Kettenstruktur. Der Ni•••Ni-Abstand beträgt 8.532 A ˚. In [Ni(cyclam)Mn(1,2-dtsq) 2 (H 2 O) 2 ]•2H 2 O liegen Zick-Coordination Polymeric 1,2-Dithiooxalato and 1,2-Dithiosquarato Complexes. Syntheses and Structures of [BaCr 2 (bipy) 2 (1,2-dtox) 4 (H 2 O) 2 ], [Ni(cyclam)(1,2-dtsq)]•2DMF, [Ni(cyclam)Mn(1,2-dtsq) 2 (H 2 O) 2 ]•2H 2 O, and [H 3 O][H 5 O 2 ][Cu(cyclam)] 3 [Cu 2 (1,2-dtsq) 3 ] 2 Abstract. 1,2-Dithioxalate and 1,2-dithiosquarate ions have a pair of soft and hard donor centers and thus are suited for the formation of coordination polymeric complexes containing soft and hard metal ions. The structures of four compounds with building blocks containing these ligands are reported: In [BaCr 2 (bipy) 2 (1,2dtox) 4 (H 2 O) 2 ] Barium ions and pairs of Cr(bipy)(1,2-dtox) 2 complexes form linear chains by the bisbidentate coordination of the dithiooxalate ligands towards Ba 2ϩ and Cr 3ϩ . In [Ni(cyclam)(1,2dtsq)]•2DMF short NϪH•••O hydrogen bonds link the NiS 2 N 4 -octahedra with C 2v -symmetry to an infinite chain. In [Ni(cyclam)Mn(1,2-dtsq) 2 (H 2 O) 2 ]•2H 2 O the 1,2-dithiosquarato ligand Einleitung
