JAMESON Institute of Inorganic Chemistry, University Zffrich, Winterthurerstrasse 190, CH-8057 Zffrich, Switzerland (Received 29 April 1982; accepted 15 September 1982) Abstract The structure of [Ni2(CsHs)3][BF4] has been rede- termined at 190 K. Formula weight 399.5, space group P212121, Z = 4. Cell at 190 K: a = 16.779 (9), b = 11.339 (8),c = 8.046 (5),/k, V= 1530.8,~3,Dx= 1.73 Mg m-3, B(Mo K~) = 2.50 mm-1. Cell at 295 K: a = 17.019(2), b = 11.454(2), c = 8.074(1),/k, V = 1573.9 ,/k3, Dx = 1.69 Mg m-3, DO = 1.66 (1) Mg m-3, B(Mo Ka) = 2.43 mm-l. The structure was refined on F to R = 0.039 using 1767 data having Fo2 > 3a(Fo2) and 201 parameters. The triple-decker sandwich-type structure was confirmed. Interatomic distances are: Ni to outer ring 1.746 (12)
