Abstract
The reaction of the LAl(SH)(µ‐O)P(OEt)2 (L=HC[C(Me)NAr]−, R=2,6‐di‐iPr2C6H3) ligand (1) with GaMe3 in toluene led to the isolation of a unique heterobimetallic aluminophosphite [κ2‐P, S‐LAl(µ‐S)(µ‐O)P(OEt)2]GaMe2 (2). Compound 2 is a potential secondary building unit (SBU) for heterometallic materials and represents the first example of structurally characterized lipophilic phosphite of the p‐block metals, in which the metal is coordinated by the phosphorus atom. Moreover, it represents the first structurally characterized example where a gallium atom is coordinated to both, sulfur and phosphorus atoms. Furthermore, it contains a rare carbon‐free “true” 5‐membered heterocycle Al‐O‐P‐Ga‐S.
