“…These facts further support the conclusion that the monomeric structures of 3 and 4 are mainly stabilized by virtue of donating of donor atoms electron density to the empty p‐type orbital of the central atoms. Similar SnN interactions have been detected in an intramolecularly coordinated diorganostannyne ArSnSnAr recently 20. In this distannyne, the Lewis basic nitrogen atoms also stabilize the emtpy p‐type orbitals.…”

“…Zudem wurden anhand von subvalenten Clustern wie [Sn 9 {Sn(NR'R'')} 6 ] (R', R'' = SiMe 3 , C 6 H 3 -2,6-iPr 2 ) [4] außergewöhnliche elektronische Strukturen und eine Vielfalt möglicher Molekülstrukturen demonstriert. Ein großes Spektrum an elementorganischen Verbindungen -von Dimeren unterschiedlicher formaler Bindungsordnungen, Ladungen und Liganden, [2,5] über Ketten, [6] Cyclen [7] und Heterocyclen [8,9] zu Polycyclen [7b, 10] trug zum Verständnis von Analogien und Gegensätzen im Vergleich mit homologen Kohlenstoffverbindungen bei, etwa im Bezug auf die Reaktivität der Sn-Sn-Bindung. An die SnSn-Einheit können weitere Heteroatome gebunden sein, etwa B-Atome [11] , [11b] PAtome [12] in [{Sn(m-PCy)} 3 ] 2À [12b] oder Chalkogenatome.…”

“…Die Sn-Sn-Bindungslänge (Sn-Sn 278.03(17) pm, ñ Sn-Sn 174 cm À1 ) rangiert im unteren Bereich bekannter Sn-Sn-Einfachbindungen. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]21] Die Sn-und S-Atome der [(RSn) 2 -(m-S) 2 ]-Einheiten bilden viergliedrige Ringe am Ende der drei Schaufelräder und sind Bestandteil dreier Paare siebengliedriger Ringe, die sich die Sn-Sn-Hantel teilen.…”

“…They can be synthesized successfully by incorporating sterically hindered substituents at the heavier Group 14 elements. For example, the amidinate‐stabilized disilylene and digermylene [{R 1 C(NR 2 ) 2 }E:] 2 (E=Si or Ge, R 1 =Ph, R 2 = t Bu; E=Ge, R 1 = t Bu, R 2 =2,6‐ i Pr 2 C 6 H 3 ),1a,c,d N ‐heterocyclic carbene‐stabilized dichlorodisilylene R→(Cl)SiSi(Cl)←R [R=:C{N(2,6‐ i Pr 2 C 6 H 3 )CH} 2 ]1e and diaryldistannylene [Ar*Sn:] 2 [Ar*=2,6‐(Me 2 NCH 2 ) 2 C 6 H 3 ]1g were reported and structurally characterized. That heavier dicarbene analogues have unprecedented electronic structure prompted our interest in exploring their chemical reactivity.…”
