Description / Table of Contents:
As was proved by determination of molecular weights, trihalogenostannic acid esters are dimeric containing tin with the coordination number of 6. Bridging atoms in the dimers are oxygen atoms, as the h k 0 projection of the structure of monoclinic SnCl3OCH3 · CH3OH shows (space group P21/n; a = 9.06 Å; b = 12.33 Å; c = 7.23 Å; ß = 92,8°). Coordinates have been determined by heavy-atom and FOURIER methods.
Notes:
Trihalogenzinnsäure-ester sind, wie Molekulargewichtsbestimmungen zeigen, dimer, wodurch sich für Sn die Koordinationszahl 6 ergibt. Als Brückenatome wirken in der dimeren Molekel Sauerstoffatome, wie die h k 0-Projektion der monoklinen Form von SnCl3OCH3 · CH3OH (Raumgruppe P21/n, a = 9,06 Å, b = 12,33 Å, c = 7,23 Å, ß = 92,8°) zeigt. Die Koordinaten wurden nach der Schweratommethode und FOURIER-Methoden bestimmt.
