The title complex, [Au(2)Cl(2)(C(26)H(21)NP(2))], has an intra-molecular Au⋯Au inter-action of 3.1669 (4) Å, but no inter-molecular Au⋯Au inter-actions in the solid state. The Cl-Au-P bond angle of 176.84 (7)° is slightly distorted from linearity. The P-C bond length to the phenyl group is shorter [1.810 (7) Å] than the P-C bond length [1.876 (7) Å] to the bridging carbon, indicative of the fle...

o bjectives: the objective of this study was to assess the effect of new bonding techniques on enamel surface. materials and methods: sixty upper central incisors were randomly divided into two equal groups. in the first group, metal brackets were bonded using trans- bondxt and, in the second group, the same brackets were bonded with maxcemelite. the shear bond strength (sbs) of both agents to ...

High real-space resolution atomic pair distribution functions ~PDF’s! have been obtained from ZnSe12xTex using neutron powder diffraction. Distinct Zn-Se and Zn-Te nearest-neighbor ~nn! bonds, differing in length by Dr50.14 Å, are resolved in the measured PDF’s, allowing the evolution with composition of the individual bond lengths to be studied. The local bond lengths change much more slowly w...

Nickel silicide has been studied with a range of computational methods to determine the nature of the Ni-Si bond. Additionally, the physical effects that need to be addressed within calculations to predict the equilibrium bond length and bond dissociation energy within experimental error have been determined. The ground state is predicted to be a (1)Σ(+) state with a bond order of 2.41 correspo...

Assigning bond orders is a necessary and essential step for characterizing a chemical structure correctly in force field based simulations. Several methods have been developed to do this. They all have advantages but with limitations too. Here, an automatic algorithm for assigning chemical connectivity and bond order regardless of hydrogen for organic molecules is provided, and only three dimen...

Composite action of any reinforced concrete member is only possible if sufficient bond strength exists between steel reinforcing bars and concrete, which can adequately transfer shear stress between them. Bond strength is a function of compressive strength of concrete and hence high strength concrete has higher bond strength [1-2]. Therefore required development length can be reduced. In order ...
