Abstract

The crystal structure (P21/c, a = 1199.7(2), b = 1304.2(4), c =
= 1639.1(4) pm, beta = 102.10(1) 0 (J.. MoKa = 71.069 pm), Z = 2) of
this compound, [CuC14H24N4] [B(C5Hs)4]2, has been determined from
diffractometer x-ray data and refined by least-squares to R = 0.055
and Rw = 0.037.
The CuTIM cation, planar except for two methylene groups,
is one of the rare cases of planar four-coordinate copper(II),
although the apical regions of the coordination sphere are occupied
by the centers of phenyf groups from two tetraphenylborate ions.
The tetraphenylborate ion has a normal conformation which
deviates slightly, but significantly, from S4 symmetry.
