The Imino Stannylene SnNH Incorporated in a Molecular Tin-Nitrogen Cage and other Tin(II)-Nitrogen Derivatives
The iminostannylene HNSn was successfully incorporated in a molecular cage of composition (Me2RSi-NSn)(3)(HNSn) with group R either being a methyl (1) or vinyl (2) substituent. An X-ray structure analysis reveals that 2 consists of a distorted Sn4N4 cube. The Sn-N(H) bond lengths [2.189(2) angstrom] are in the range for Sn4N4 hetero cubanes. When stored in a toluene solution the clusters 1 and 2 decompose slowly into the symmetric cubanes (Me2RSi-NSn)(4) [R = Me (3), CHCH2 (4)] and an amorphous and insoluble powder of composition HNSn. The decomposition follows a first order rate law as established for 2 with a half life time t(1/2) = 320 d at 20 degrees C. The compounds 1 and 2 can thus be regarded as a result of interaction between three entities {Me2RSi-NSn} and one entity {HNSn}. We also isolated the twistane-like Me2Si(NtBu)(2)Sn(2)NtBu (5) in a crystalline form. The central structure of this molecule, which has almost C-2v symmetry, has a trigonal bipyramid Sn2N3 unit with the nitrogen atoms occupying the equatorial plane. Each nitrogen atom has a tert-butyl ligand and two of the N atoms are further connected by the dimethylsilyl group. There is one nitrogen atom in an almost planar environment (only bonding to tert-butyl and two tin atoms) with a remarkable short Sn-N bond length of 2.048(5) angstrom. Both tin atoms in cage 5 can bond to Cr(CO)(5) to form [Me2Si(NtBu)(2)Sn(2)NtBu][Cr(CO)(5)](2) (6) with an almost linear Cr-Sn center dot center dot center dot Sn-Cr arrangement and Sn-Cr bond lengths of 2.581(1) angstrom (X-ray diffraction).
