Abstract

Sn(ii) derivatives of the aminoalcohols (t)Bu(H)NC(Me)(H)CH(2)OH (Htbap, ), (R(1)R(2)NCH(2))(2)C(H)OH (R(1) = R(2) = Me, , Hbdmap; R(1) = (t)Bu, R(2) = H, , Hbtbap), (R(1)R(2)NCH(2))(3)COH (R(1) = R(2) = Me, , Htdmap; R(1) = (t)Bu, R(2) = H, , Httbap) have been synthesised by reaction of the alcohol with Sn[N(SiMe(3))(2)](2). The structures of the ligands , .H(2)O, along with Sn(ttbap)(2) have been determined; the latter is pseudo-trigonal bipyramidal with nitrogen atoms in axial sites and oxygen atoms and a stereochemically-active lone pair in the equatorial positions. Sn(ttbap)(2) reacts with Fe(2)(CO)(9) in 2 : 1 ratio (Sn : Fe = 1 : 1) to afford the donor-acceptor complex (ttbap)(2)Sn:-->Fe(CO)(4), while in 1 : 1 ratio (Sn : Fe = 1 : 2) the Sn(0) complex (Httbap)Sn[Fe(CO)(4)](2) is formed, in which Httbap is a neutral zwitterionic form of the ligand. The structures of both bimetallic species are reported. Thermal decomposition of (Httbap)Sn[Fe(CO)(4)](2) under low-pressure CVD conditions gives a film containing a mixture of cubic-Sn, cubic-Fe and the hexagonal intermetallic phase Fe(3)Sn.
