Abstract

The calcium(II) β-diketonate complexes [Ca(dppd)₂(EtOH)_0.5]_n · C₇H₈ (1) and [Ca(dppd)₂(H-dppd)] (2) have been synthesized from the reactions of [Ca(OEt)₂(EtOH)₄]_n with 2 and 3 molar equiv. of H-dppd (H-dppd = 1,3-diphenylpropane-1,3-dione), respectively. The reaction of the tetra-ethanol solvated calcium ethoxide with 2 and 1 molar equiv. of H-dppd and pmdeta [Me₂NCH₂CH₂N(Me)CH₂CH ₂NMe₂], respectively, gave [Ca(dppd)₂(pmdeta)] (3). A single crystal X-ray structural study of complex 3 has shown it be monomeric. The reaction of [Sr(OEt)₂(EtOH)₄]_n with 3 molar equiv. of H-tmhd (H-tmhd = 2,2,6,6-tetramethylheptane-3,5-dione) also yielded [Sr(tmhd)₂(H-tmhd)] (4).
