Crystal structures of (Ph2CNLi·NC5H5)4 and [CILi·OP(NMe2)3]4; discrete tetrameric pseudo-cubane clusters with bridging of Li3 triangles by nitrogen and by chlorine atoms

Abstract

X-Ray crystallographic studies of the title compounds (Ph₂CNLi·NC₅H₅)₄, (1), and [CILi·OP(NMe₂)₃]₄, (2) show them to have pseudo cubane tetrameric structures in which triply-bonding methyleneamino -nitrogen atoms [(1)] or chlorine atoms [(2)] hold together the tetrahedral Li₄ frameworks.
