etrakis-mu-acetato-bis(acetonitrile-N)dicopper(II) bisacetonitrile (1)
was synthesized and characterized by IR spectroscopy and by an X-ray
structure determination [Space group P2(1)/n, Z = 2, lattice dimension
s at -70 degrees C: a = 1063.2(1), b = 1018.4(1), c=1088.3(1) pm, beta
= 101.59(1)degrees, R-1 = 0.048]. According to the structural data th
e blue compound consists of centrosymmetric dimers [Cu-2(OAc)(4)(NCMe)
(2)] and noncoordinated acetonitrile molecules.
