Abstract: The lathanum and neodymium complexes [C4H9O]+[Ln(S2CNC4H8)4]-were prepared by reacting LnCl3(Ln=La and Nd)with NH4(S2CNC4H8)in THF.Both structures were solved by Patterson and Fourier methods and refined by full matrix least-square techniques to R 0.064 and 0.051. The compound [C4H9O]+[La(S2CNC4H8)4]- is rhombic, space group P212121 with cell dimensions: a=9.985(5),b=14.181(5), c=24.212(7)Å,α=β=γ=90°,Z=4. The analogous neodymium compound[C4H9O]+[Nd(S2CNC4H8)4]- is monoclinic, space group P21/c, with cell dimensions; a=12.212(5), b=15.199(11), c=18.301(10)Å, β=98.61(4)°, Z=4. The crystals consist of [C4H9O]+ and CLn(S2CNC4H8)4]- ions, in the anions the lanthanum and neodymium atoms are coordinated to eight sul fur atoms forming a distorted dodecahedron, |
