dot(thf)(2) (Ln = Yb, Eu and Sm) with one equivalent of DIPP(H)N-BH-N(H)DIPP ((DIPP)NBN-H(2), DIPP = 2,6-iPr-phenyl) gave the first Ln(II) bora-amidinate complexes which crystallized in the presence of THF as (DIPP)NBN-Ln center dot(thf)(4). Although only the Sm and Eu complex crystallize isomorphic, all three show similar structures. The very small N-Ln-N' bite angles of 59.74(6)-63.28(9)degrees leave a
(2-Me(2)N-alpha-Me(3)Si-benzyl)(2)Ln 中心点 (thf)(2)(Ln = Yb、Eu 和 Sm)与一当量的 DIPP(H) 的反应N-BH-N(H)DIPP ((DIPP)NBN-H(2), DIPP = 2,6-iPr-苯基) 得到第一个 Ln(II) 硼脒复合物,其在 THF 存在下结晶为( DIPP)NBN-Ln 中心点(thf)(4)。尽管只有 Sm 和 Eu 复合物结晶同构,但所有三种都显示出相似的结构。59.74(6)-63.28(9) 度的非常小的 N-Ln-N' 咬合角使大部分金属配位球可用于中性 thf 配体。
