Abstract

Heteroleptic aminotroponiminate complexes of calcium and strontium have been prepared. The monomeric calcium complex [{(iPr)2ATI}CaI(THF)3] 1 ((iPr)2ATI = N-isopropyl-2-(isopropylamino)troponiminate) and the corresponding dimeric strontium compound [{(iPr)2ATI}SrI(THF)2]22 were obtained by reaction of [{(iPr)2ATI}K] and MI2. Whereas the mixed ligand compound of composition [{(iPr)2ATI}Ca(iPrAT)]23 (iPrAT = 2-(isopropylamino)troponate) was not obtained via a salt metathesis but by reaction of [Ca{N(SiMe3)2}2(THF)2] with {(iPr)2ATI}H and (iPrAT)H, the diphosphanylamido complex [{(iPr)2ATI}Ca{(Ph2P)2N}(THF)2] 4 was obtained by reaction of CaI2 with the potassium compounds [{(iPr)2ATI}K] and [K(THF)n][N(PPh2)2]. The single crystal X-ray structures of all compounds were established and the latter compound shows a η2-coordination mode of the ligand via the nitrogen and one phosphorus atom.
