Crystal structures of [Co(MH)2(Thio)2][BF 4]·H2O (I) and [Co(DH)2(NH 3)2][BF4] (II), where MH- is H 3C-C(NOH)-C(NO-)-H and DH is H3C-C(NOH)- C(NO-)-CH3, were determined by X-ray diffraction. The crystals are monoclinic, space group C2/c, unit cell parameters (for I and II, respectively): a = 22.018(2) Å,b = 7.943(1) Å, c = 11.681(1) Å, β = 92.68(1)° and a = 21.436(2) Å, c = 6.400(2) Å, β = 12.389(2) Å, β = 113.13(1)°. In both cases, the Co(III) coordination polyhedron is a centrosymmetrical trans-octahedron, N 4S2 for I and N6 for II. In the crystals of I and II, the complex cations and the outer-sphere [BF4]- anions (and the crystal water molecules in I) form elaborate hydrogen bonding system. |
