It enables the preparation of rare or even, up to now, unknown, solution-stable heteroleptic barium complexes. The syntheses and structural features for the first molecular barium fluoride and the first barium stannylide, with an unsupported Ba-Sn bond, are described, along with other carbazolate barium species: an amide (both a remarkably stable starting material and an excellent hydrophosphination precatalyst), iodide, and silanylide. DFT analysis of bonding patterns in the barium stannylide and barium silanylide highlights a prevailingly ionic barium-tetrelide bond with a small covalent contribution. %G English %2 https://univ-rennes.hal.science/hal-02498789/document %2 https://univ-rennes.hal.science/hal-02498789/file/Chapple%20et%20al-2020-Bis%28imino%29carbazolate%20-%20a%20master%20key%20for%20barium%20chemistry.pdf %L hal-02498789 %U https://univ-rennes.hal.science/hal-02498789 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR-CD %~ SCR_OMC2012 %~ ISCR-OMC %~ ISCR-CTI %~ STATS-UR1 %~ UR1-SPM %~ GENCI %~ ISCR-PRATS %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ ANR %~ UR1-MMS %~ TEST2-HALCNRS
