title: A cyclo-P6 Ligand Complex for the Formation of Planar 2D Layers.
abstract: The all-phosphorus analogue of benzene, stabilized as middle deck in triple-decker complexes, is a promising building block for the formation of graphene-like sheet structures. The reaction of [(CpMo)2 (μ,η(6) :η(6)-P6)] (1) with CuX (X=Br, I) leads to self-assembly into unprecedented 2D networks of [{(CpMo)2P6}(CuBr)4 ]n (2) and [{(CpMo)2 P6}(CuI)2]n (3). X-ray structural analyses show a unique deformation of the previously planar cyclo-P6 ligand. This includes bending of one P atom in an envelope conformation as well as a bisallylic distortion. Despite this, 2 and 3 form planar layers. Both polymers were furthermore analyzed by (31)P{(1)H} magic angle spinning (MAS) NMR spectroscopy, revealing signals corresponding to six non-equivalent phosphorus sites. A peak assignment is achieved by 2D correlation spectra as well as by DFT chemical shift computations.
