An Extremely Bent Cyanide Bridge in Crystals of [(CN)3 Pt(хCN)Cu(NH3 )4 ]. Influence of Electrostatic Forces on the Nature and
Geometry of Bridging Cyanides in the Solid State.
? The title
compound (III) crystallizes in the orthorhombic space group Pnma with Z = 4
(single crystal XRD at 102 and 233 K). The Pt and Cu atoms are linked by
a CN bridge with a C?N?Cu angle of 120.1 and C?N and N?Cu distances of
1.147 and 2.394 A?, respectively. The extreme deviation from linearity observed
for the C?N?Cu angle is explained by the presence of an extensive electrostatic (N)HиииN(C) net. ? (ESCORIHUELA, IMMACULADA; FALVELLO,
