The crystal structure of a new ferrocenyl P,N ligand: 1-[(2,2-dimethylhydrazin-1-ylidene)methyl]-1'-(diphenylphosphorothioyl)ferrocene
Résumé
The asymmetric unit of the title compound, [Fe(C8H11N2)(C17H14PS)], contains two independent molecules (A and B) with very similar conformations. Each molecule is built up from a ferrocene unit substituted in the 1 and 1' positions by a protected sulfur diphenylphosphine and by a dimethylhydrazine, -C(H)=N-N(CH3)2, fragment. The two independent molecules are linked by a C-H...N hydrogen bond. In the crystal, the A-B dimer is linked by a pair of C-H...S hydrogen bonds, forming a centrosymmetric four-molecule arrangement. These units are linked by C-H...[pi] interactions, forming a supramolecular three-dimensional structure.
