1995
Crystals of tris(2-mercaptopyridine N-oxido)cobalt(III) monohydrate hemimethanol solvate, fac[Co(C 5 H 4 NOS) 3 ].H 2 O.1/2CH 3 OH (1), contain fac[Co(III)(mpo) 3 ] (Hmpo=2-mercaptopyridine N-oxide), H 2 O and MeOH molecules linked by hydrogen bonds. The asymmetric unit consists of two molecules of the cobalt complex, two water and one methanol molecule. The asymmetric unit of the closely related complex tris(2-mercaptopyridine N-oxido)cobalt(III) 1/3-methanol solvate, fac[Co(C 5 H 4 NOS) 3 ].1/3CH 3 OH (2), contains three discrete Co(mpo) 3 molecules and one MeOH molecule which is linked to one of the Co(mpo) 3 units via a hydrogen bond. The Co III complex molecules in (1) and (2) do not differ significantly. Each Co atom is coordinated by an O 3 S 3 donor set which defines a distorted facial octahedron. Three mpo ligands are chelated to each Co atom, the average O-Co-S bite angle is 87.5 (2) for (1) and 87.4 (2) o for (2). The average Co-S and Co-O distances are 2.205 (3) and 1.942 (2) A, respectively, for (1), and 2.205 (3)and 1.951 (5) A, respectively, for (2)
