Abstract
Synthetic and structural details of flexible scorpionate ligand based on 2-mercaptopyridine (Bmp) supported heavier alkaline earth metal complexes with metal–sulfur bonds (metal = Sr, Ba) have been presented.
Highlights
The scorpionate ligands such as [hydrotris(pyrazolyl)borate]1 and [dihydrobis(pyrazolyl)borate]2 rst reported by Tro menko were generally thought of as innocent spectator ligands in transition metal chemistry,[3,4] modifying the properties of the metal centre without getting directly involved in its reactivity.[5]
The Owen group has reported on the sodium salt of the borate (Tmp) and hydrobis(2-thiopyridone)borate (Bmp) ligand; its solid-state structure has not been established.8a We found this very useful to report the solid-state structure of NaBmp and compare with the solid-state structures of alkaline earth metal complexes
Each sodium atom is coordinated with one THF molecule and the geometry around the sodium ions can be best described as a distorted tetrahedral. Both the BH2 groups from the Bmp ligands are bonded with the sodium ions through hydrogen atoms via m (H1B and H2B) and h1 (H1A and H2A) bonds
Summary
The scorpionate ligands such as [hydrotris(pyrazolyl)borate]1 and [dihydrobis(pyrazolyl)borate]2 rst reported by Tro menko were generally thought of as innocent spectator ligands in transition metal chemistry,[3,4] modifying the properties of the metal centre without getting directly involved in its reactivity.[5]. Complex 1 was re-crystallised from concentrated THF solution at 15 C and the solid-state structure was con rmed using single-crystal X-ray structure analysis. The solid-state structure of sodium complex 1 con rmed the k2 SScoordination of the Bmp ligand.
