TL;DR: In this article, the X-ray crystal structure analysis of cis-[PtPh2(Ph2PCH2PPh2)] suggests that the unusually low PtP coupling constant is a consequence of distortion of the valency angles at the platinum and phosphorus atoms; the restrictive geometry of the chelate ring does not effect the lengths of the metal ligand bonds.

TL;DR: Olefins with between 4 and 24 and preferably between 10 and 20 carbon atoms are selectively dimerized by using zeolite catalysts in acid form which are partially exchanged with salts of metals having a valency of two or more as discussed by the authors.

TL;DR: In this paper, the structural changes occurring upon substitution of several lanthanides (Ln) for Y in the high-T c superconductor YBa 2 Cu 4 O 8 have been studied by neutron powder diffraction in order to establish the influence of the size and valency of the dopant ions.

TL;DR: Substitutional doping of a-6Ni1-x: H and structural properties have been systematically investigated in this paper, where it was found that the efficiency of phosphorus doping is rather low with respect to that of boron doping.
Abstract: Substitutional doping of a-SixNi1-x: H and the structural properties have been systematically investigated. Valency control of a-SixN1-x: H is found to be possible, although the efficiency of phosphorus doping is rather low with respect to that of boron doping. Vibrational spectra of boron-doped films showed the presence of a considerable amount of the BN bonds, which reduces the amount of the SiN bonds in the network, while phosphorus-doped films contain no PN bonds. Excellent thermal stability of undoped a-SixN1-x: H and the absence of photostructural change are also confirmed.
