Et3Sb at low temperature gives hexacoordinate [(AP-AP)H]SbEt3 (4) which decomposes slowly in vacuum with the liberation of ethane yielding pentacoordinate complex [(AP-AP)]SbEt2 (5). [(AP-AP)H]2− is O,N,O′-tridentate amino-bis-(3,5-di-tert-butyl-phenolate-2-yl) dianion and [(AP-AP)]3− is amido-bis-(3,5-di-tert-butyl-phenolate-2-yl) trianion. The decomposition of 4–5 accelerates in the presence of air
