Treatment of M (OTf) 2 [from MO+ 2 HOTf; OTf= OSO2CF3 and M= Ca 1, Sr 2 or Ba 3] with 2MOAr or 2MNR2 (M= Na or K, Ar= C6H2But2-2, 6-Me-4; R= SiMe3) in thf at 0° C affords [Ca (OAr) 2 (thf) 3] 4,[M (OAr) 2 (thf) 4](M= Sr 5 or Ba 6),[M (NR2) 2 (thf) 2](M= Ca 7 or Sr 8) or [Ba (NR2)(µ-NR2) 2Na (thf) 2] 9; the new compounds 1–3 have been characterised by their NMR spectra in pyridine, and the pyridine adduct of 3 also by X-ray diffraction: ...
