Abstract
The calcium(II) beta-diketonate complexes [Ca(dppd)(2)(EtOH)(0.5)]. C7 H8 (1) and [Ca(dppd)(2)(H-dppd)] (2) have been synthesized from the re actions of [Ca(OEt)(2)(EtOH)(4)](n) with 2 and 3 molar equiv. of H-dpp d (H-dppd = 1,3-diphenylpropane-1,3-dione), respectively. The reaction of the tetra-ethanol solvated calcium ethoxide with 2 and 1 molar equ iv. of H-dppd and pmdeta [Me2NCH2CH2N(Me)CH2CH2NMe2], respectively, ga ve [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)(Et OH)(4)](n) with 3 molar equiv. of H-tmhd (H-tmhd = 2,2,6,6-tetramethyl heptane-3,5-dione) also yielded [Sr(tmhd)(2)(H-tmhd)] (4).
