Balmer, Markus published the artcileLow-Valent Group 14 Phosphinidenide Complexes [({SIDipp}P)2M] Exhibit P-M pπ-pπ Interaction (M=Ge, Sn, Pb), Application of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is Chemistry – A European Journal (2020), 26(1), 192-197, database is CAplus and MEDLINE.
Herein, the synthesis of new low-valent Group 14 phosphinidenide complexes [({SIDipp}P)2M] exhibiting P-M pπ-pπ interactions (SIDipp = 1,3-bis(2,6-diisopropylphenyl)-imidazolidin-2-ylidene, M = Ge, Sn, Pb), is presented. These compounds were studied by structural, spectroscopic, and quantum-chem. methods. Furthermore, the monosubstituted compounds [(SIDippP)MX]2 (M = Sn, X=Cl; M = Pb, X = Br) are presented, which show dimeric structures instead of multiple bonding interaction.
