Abstract
The trans-dimer of (9-HS-9-BBN)(2) (1)(2), obtained from H2S with (9H- 9-BBN)(2) or with (9-BBN)(2)S, crystallizes in the monoclinic space gr oup C2/m [lattice constants (at 120 K): a=15.279(2), b=15.909(3), c=6. 822(4) Angstrom; beta=91.05(4)degrees] with a planar B(2)S(2)ring. The cis-dimer of (9-HSe-9-BBN)(2) (2)(2), obtained from (9-BBN)(2)Se with aniline, crystallizes in the monoclinic space group P2(1)/n [lattice constants (at 225 K): a=6.892(1), b=20.623(3), c=12.226(2) Angstrom; b eta=97.28 degrees] with an folded B(2)Se(2)ring.
