Syntheses and properties of bis{bis(trimethylphosphine)tetrahydrodiboron}copper(1+) halide (halide = chloride, iodide) and x-ray crystal structure of the iodide

TLDR: In this article, X-ray crystal structure analysis of the iodide showed that each ligand is coordinated to the copper atom through two vicinal hydrogen atoms and the copper atoms is ligated with four hydrogen atoms tetrahedrally.

Abstract: Chloride and iodide salts of bis{bis(trimethylphosphine)tetrahydrodiboron-H 1 ,H 2 } copper(I), [Cu{B 2 H 4 •2P(CH 3 ) 3 } 2 ]X (X=Cl, I), were prepared by the reactions of B 2 H 4 •2P(CH 3 ) 3 with the copper(I) halides. X-ray crystal structure analysis of the iodide shows that each ligand is coordinated to the copper atom through two vicinal hydrogen atoms and the copper atom is ligated with four hydrogen atoms tetrahedrally. Crystal data: monoclinic with the space group I2/a
