K. Merzweiler et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF [(CP(C O)(2)FE)(2)SN(F)FBF3], Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 49(3), 1994, pp. 425-429
[{Cp(CO)(2)Fe}2SnCl2] reacts with AgBF4 to form [{Cp(Co)(2)Fe}Sn-2(F)F
BF3] 1.1 crystallizes in two monoclinic modifications with a = 1018.2(
4), b = 1321.1(5), c = 1364.8(5) pm, beta = 104.96(4)degrees (la), and
a = 983.1(2), b = 1760.2(6), c = 1060.4(3) pm, beta = 104.28(2)degree
s (1b). 1a and 1b contain a nearly tetrahedrally coordinated tin atom
which is bonded to two {Cp(CO)(2)Fe} fragments, a F atom and a BF4 gro
up.
