    Description / Table of Contents: Directed Synthesis of Sulfinato-O and -S Complex of Transition Metals, XI. Linkage Isomerism in Sulfinato Complexes of Zinc(II)Starting from the sulfinato-O, O′ complexes (RSO2)2Zn(OH2)2(1a, b) the mono-, bis-, and tris(2, 2′-bipyridyl) complexes 2a, b, 3a, b, and 4a, b are produced according to equation (1) by stepwise addition of 2, 2′-bipyridyl. In the case of the bis(2, 2′-bipyridyl) complexes 3a, b the linkage-isomeric sulfinato-O and -S complexes 3aO, 3bO, and 3aS, 3bS are obtained. From 4a, b 1 mole of 2, 2′-bipyridyl can be eliminated reversibly with acetone according to equation (7) with formation of 3aO and 3aO. The newly prepared compounds were characterized on the basis of their i. r. spectra. In the case of 4a, b DTA, TG, and DTG measurements were carried out.
    Notes: Gemäß Gl. (1) gelingt, ausgehend von den Sulfinato-O, O′-Komplexen (RSO2)2zn(OH2)2 (1a, b), die schrittweise Addition von 2,2′-Bipyridyl, wobei die Mono-, Bis-und Tris(2,2′-bipyridyl)-Komplexe 2a, b, 3a, b und 4a, b entstehen. Im Falle der Bis(2,2′-bipyridyl)-Komplexe 3a, b wurden die bindungsisomeren Sulfinato-O-und-S-Komplexe 3aO, 3bO und 3aS, 3bs erhalten. Aus 4a, b läβt sich mit Aceton reversibel ein mol 2, 2′-Bipyridyl gemäß Gl. (7) unter Bildung von 3aO und 3bO abspalten /die neu dargestellten Verbindungen werden IR-spektroskopisch charakterisiert. Im Falle von 4a, b sind DTA-, TG- und DTG-Messungen durchgeführt worden.
