Crystal structure and Hirshfeld surface analysis of (nitrato-κ ,')(1,4,7,10-tetra-aza-cyclo-dodecane-κ )nickel(II) nitrate.

The crystal structure of the title compound, [Ni(CHN)(NO)]NO, at room temperature, has monoclinic (2/) symmetry. The structure displays inter-molecular hydrogen bonding. The nickel displays a distorted bipyramidal geometry with the symmetric bidentate bonded nitrate occupying an equatorial site.

Iridium Complexes of a Bis(-pyrrolyl)boryl/Bis(phosphine) PBP Pincer Ligand.

This work reports the synthesis of a bis(pyrrolylphosphino)phenyl borane (PBP)Ph () and its incorporation of Ir by metal insertion into B-Ph to afford the dipyrrolylboryl/bis(phosphine) pincer complex (PBP)Ir(Ph)Cl (). Hydrogenolysis of afforded (PBP)Ir(H)Cl (). Compound was converted into (PBP)IrCl () via reaction with -chlorosuccinimide, and exposure of to CO produced (PBP)IrCl(CO) ().

Exploring the potential of malononitrile functionalized donor-acceptor systems for non-volatile memory device applications.

A novel series of D-bridge-A type organic small molecules has been designed, synthesized, and evaluated for non-volatile resistive switching write-once read-many (WORM) memory application. This study explores structure-property relationships by coupling electron-deficient malononitrile units with donors such as dibenzofuran, dibenzothiophene, and triphenylamine. Photophysical investigations revealed significant intramolecular charge transfer interaction, while electrochemical analyses demonstrated optimal band gaps ranging from 2.

Transition Metal as Template: Reversing the Synthesis Logic in the Preparation of Pincer Complexes.

The conventional synthetic approach to transition metal pincer complexes calls for the preparation of the tridentate pincer (pro)ligand first, with subsequent introduction of the transition metal center as the last step. This work demonstrates that the alternative synthetic logic, where the central main group element is introduced last, can be applicable to a number of PEP pincer complexes (E=B, Al, Si, P) derived from phosphinophenols and phosphinopyrroles. This approach obviates the need to isolate well-behaved propincer precursors, and instead relies on the formation of phosphine-metal adducts first, whose nature determines the stoichiometry of the needed main group reagent to complete the synthesis.

Synthesis of Os Hydride Complexes Supported by the Diarylamido/Bis(phosphine) PNP Ligand and Attempts at Using (PNP)Ru and (PNP)Os Complexes in C-H Borylation Catalysis.

This manuscript describes the synthesis of Os complexes supported by the diarylamido/bis(phosphine) PNP pincer ligand. Compound (PNP)OsH(CO) () was prepared by analogy with the previously reported . However, attempts to make (PNP)OsH () analogously to resulted in the formation of an unexpected compound () that is a product of addition of a BH unit across the Os-N bond in .
