Diiodacetylenkomplexe von Wolfram(IV). Die Kristallstruktur von PPh4[WCl5(C2l2)] · 0,5 CH2Cl2

Abstract: Wolframhexachlorid und Diiodacetylen reagieren in CCl4‐Lösung unter Bildung des über Chlorobrücken dimerisierten [WCl4(ICCI)]2, das sich mit PPh4Cl in Dichlormethan in PPh4[WCl5(ICCI)] · 0,5 CH2Cl2 überführen läßt. Beide Diiodacetylenkomplexe enthalten den seitwärts an das Wolfram koordinierten C2I2‐Liganden, der hierdurch eine ungewöhnliche thermische Stabilität erreicht. Die Kristallstruktur des Tetraphenylphosphonium‐Salzes wurde mit Hilfe von Röntgenbeugungsdaten ermittelt (3879 unabhängige, beobacht… Show more

“…Complex 6 -BF 4 is the second C 2 I 2 alkyne complex proven by XRD and the first one within an organometallic framework . The W IV complex (PPh 4 )­[WCl 5 (C 2 I 2 )] published by Dehnicke displays comparable C–C bond lengths of 1.26/1.27 Å . The molecular structure of 5 -OTf displays similar features; however the structure data exhibit larger standard deviations because of disorder problems.…”
