Understanding our future through Open Access research about our past...

Strathprints makes available scholarly Open Access content by researchers in the Centre for the Social History of Health & Healthcare (CSHHH), based within the School of Humanities, and considered Scotland's leading centre for the history of health and medicine.

Research at CSHHH explores the modern world since 1800 in locations as diverse as the UK, Asia, Africa, North America, and Europe. Areas of specialism include contraception and sexuality; family health and medical services; occupational health and medicine; disability; the history of psychiatry; conflict and warfare; and, drugs, pharmaceuticals and intoxicants.

Abstract

The ligand orientations and Li–N distances in the title compounds show that their µ-3-imino units NC(Ph)R (R = But or NMe2) function as 3-electron ligands, forming one 2-centre LiN bond and one 3-centre Li2N bond to isosceles triangles of bridged metal atoms, prompting treatment of each hexamer [LiNC(Ph)R]6 as a pair of stacked cyclic trimers [LiNC(Ph)R]3; extension of this ring-stacking principle allows many other structures to be rationalised in lithium chemistry and facilitates structural predictions.
