Abstract

The structures of the title compounds, [SnCl(4)(C(2)H(3)N)(2)] x C(2)H(3)N*-, [SnCl(4)(C(3)H(5)N)(2)] x C(3)H(5)N, [SnCl(4)(C(4)H(7)N)(2)], [SnCl(4)(C(7)H(11)N)(2)] and [SnCl(4)(C(8)H(7)N)(2)], were determined with the intention of examining the effect of various substituent types in nitrile ligands, RCN, behaving in a common sigma-donor situation [in this case, as cis-bis complexes with SnCl(4), viz. [SnCl(4)(RCN)(2)]], on (i) the strength of complex formation with the metal atom and (ii) other bonding behaviour of the metal (for example, trans effects). The five structures exhibit no non-trivial systematic perturbation that can be said to be contingent on the substituent type.

“…6). The CuN distance of 1.129(2) Å in the [o-TolCNH] + cation is slightly shorter than in [(o-TolCN) 2 SnCl 4 ] (1.142(2) Å and 1.139(2) Å) 37 or [(o-TolCN)CuCN] (1.141(4) Å). 38 [p-C 6 H 4 (CNH) 2 ][AsF 6 ] 2 crystallizes in the monoclinic space group P2 1 /c with the cation located on an inversion center.…”
