{Bis[5-methyl-3-(trifluoro­meth­yl)pyrazol-1-yl]borato}{tris­[5-methyl-3-(trifluoro­meth­yl)pyrazol-1-yl]borato}cobalt(II): a structure containing a B—H⋯Co agostic inter­action

The title compound, [Co(C(10)H(10)BF(6)N(4))(C(15)H(13)BF(9)N(6))], is a neutral Co(II) complex which contains one each of the anionic ligands, bis­(3-trifluoro­methyl-5-methyl­pyrazol-1-yl)borate (Bp) and tris­(3-trifluoro­methyl-5-methyl­pyrazol-1-yl)borate (Tp). A distorted octa­hedral coordination geometry results from ligation of an H atom, which is part of an agostic B—H⋯Co inter­action (H⋯Co = 2.17 Å), and by five imine N atoms, two from a Bp ligand and three from a Tp ligand. In the crystal, mol­ecules form layers parallel to the (10[Image: see text]) planes, and the layers are linked along the a axis by C—H⋯F hydrogen bonds. An intra­molecular C—H⋯F inter­action also occurs.
