Synthesis and crystal structure of Ba26B12Si5N27 containing [Si2] dumbbells

“…2 The bond lengths of the B-N and the angles of N-B-N are in the ranges of 1.317(11)-1.331(10) Å and 174.7(7)-178.4 (14)°, respectively. These values agree with those reported for the compounds containing [BN 2 ] 3-[2, [3][4][5][6][7][8][9][10][11][12][13]. As shown in Fig.…”

“…The [BN 2 ] 3-groups composed of central boron atoms linearly or almost linearly coordinated by two nitrogen atoms are isoelectronic to CO 2 . Multinary compounds have also been prepared by combining alkaline-earth cations AE 2 þ ¼Mg 2 þ , Ca 2 þ , Sr 2 þ , Ba 2 þ and [BN 2 ] 3-with N 3-(Ca 3 [BN 2 ]N) [3], O 2-(Ba 4 [BN 2 ] 2 O) [4], H À (Ca 2 [BN 2 ]H) [5], and halogen anions X -¼F -, Cl -, I -, Br -(AE 2 [BN 2 ]X [6][7][8][9][10][11][12], Ba 3 [BN 2 ] 5 F [13], Mg 8 [BN 2 ] 5 I [9]). Ba 3 Ge 2 N 2 [14] and Sr 3 Ge 2 N 2 [15] contain nitridogermanide anions [GeN 2 ] 4-and one-dimensional trans chains of Zintl polyanions 1 1 [Ge 2-].…”
