Abstract

New neutral [Sr(Q)2(L)n]m or ionic (imH2)2[Sr2(Q)6] air stable complexes (QH = 1-phenyl-3-methyl-4-R(C[double bond, length as m-dash]O)-pyrazol-5-one; in detail Q = QT for R = CH2CMe3, Q = QP for R = Ph and Q = QF for R = CF3; n = m = 1 for L = tetraglyme (2,5,8,11,14-pentaoxapentadecane); n = m = 2 for L = H2O; n = 2 and m = 1 for moeH (2-methoxyethanol), dmaeH (N,N-dimethylaminoethanol) or phen (1,10-phenanthroline); imH = imidazole) have been synthesized and fully characterized. The X-ray crystal structures of [Sr(QT)2(moeH)2]2 and of (imH2)2[Sr2(QT)6] have been determined. The compound [Sr(QT)2(moeH)2]2 contains an eight-co-ordinate Sr atom in a square antiprismatic environment, due two bidentate chelating Q donors and two bidentate 2-methoxyethanol ligands. The compound (imH2)2[Sr2(QT)6] is composed of two imidazolium cations and a dianionic fragment [Sr2(QT)6]2−, which is a centrosymmetric dimer containing four terminal and two bridging Q donor ligands.
