“…One reason is that they can be prepared by straightforward synthetic methodologies [ 8 , 9 , 10 ], and that many of them are commercially available. Hence, they attained great interest in, for example, the deposition of metal or metal oxide thin layers by applying diverse deposition techniques, including CVD (=chemical vapor deposition) [ 1 , 11 , 12 , 13 , 14 ], ALD (=atomic layer deposition) [ 15 , 16 , 17 , 18 , 19 ], and spin-coating [ 20 , 21 , 22 ]. In addition, they received great interest in the synthesis of (hetero)multimetallic complexes [ 23 , 24 , 25 , 26 , 27 , 28 , 29 ] as catalysts in organic synthesis [ 30 , 31 , 32 ] and as anticancer drugs (especially copper and rhodium β-diketonates) [ 33 , 34 , 35 ].…”

The synthesis of FcC(O)CH(R)C(O)Fc (Fc = Fe(η5-C5H4)(η5-C5H5); R = H, 5; nBu, 7; CH2CH2(OCH2CH2)2OMe, 9), [M(κ2O,O′-FcC(O)CHC(O)Fc)n] (M = Ti, n = 3, 10; M = Fe, n = 3, 11; M = BF2, n = 1, 12), and 1-R’-3,5-Fc2-cC3HN2 (R’ = H, 13; Me, 14; Ph, 15) is discussed. The solid-state structures of 5, 7, 9, 12, 13, 15, and 16 ([TiCl2(κ2O,O′-PhC(O)CHC(O)Ph)2]) show that 7 and 9 exist in their β-diketo form. Compound 13 crystallizes as a tetramer based on a hydrogen bond pattern, including one central water molecule. The electrochemical behavior of 5–7 and 9–16 was studied by cyclic and square-wave voltammetry, showing that the ferrocenyls can separately be oxidized reversibly between −50 and 750 mV (5–7, 9, 12–15: two Fc-related events; 10, 11: six events, being partially superimposed). For complex 10, Ti-centered reversible redox processes appear at −985 (TiII/TiIII) and −520 mV (TiIII/TiIV). Spectro-electrochemical UV-Vis/NIR measurements were carried out on 5, 6, and 12, whereby only 12 showed an IVCT (intervalence charge-transfer) band of considerable strength (νmax = 6250 cm−1, Δν½ = 4725 cm−1, εmax = 240 L·mol−1·cm−1), due to the rigid C3O2B cycle, enlarging the coupling strength between the Fc groups.

This chapter describes the use of metal enolates as precursors for the deposition and growth of nano‐sized materials of a large variety of metal, mixed metal‐metal oxide, and alloy layers and patterns, an area that has rapidly developed during the last couple of decades. As metal enolates, mostly mononuclear main group, transition metal, and rare earth metal complexes featuring various β‐diketonate or β‐ketoiminate ligands have been used. Based on their intrinsic properties, for example, reactivity, transparency, conductivity, and magnetism, a large variety of metal and/or metal oxide deposits are available at present. As deposition processes, mainly gas‐phase (e.g., CVD2–9 and ALD8–19) or liquid‐phase procedures (including spin‐coating, dip‐coating, sol–gel, and printing techniques) were used. Controlled decomposition of the appropriate metal enolates allows the generation of diverse metal and metal oxide materials, for example, dense or porous thin layers and nanomaterials in the form of particles, dots, rods, tubes, and wires. Where appropriate, the similarities and differences, including elementary decomposition steps that are common for the respective metal enolate precursors, are discussed as well.

The reaction of [Ru 3 (CO) 12 ] (1) with six equiv. of FcC(O)CH 2 C(O)R (2a, R = Me; 2b, R = Fc; Fc = Fe(η 5-C 5 H 4)(η 5-C 5 H 5)) produced the Ru II compounds [Ru(CO) 2 (FcC(O)CHC(O)R) 2 ] (3a, R = Me; 3b, R = Fc) in moderate yields. IR studies and singlecrystal X-ray analysis (3a) confirmed that the CO ligands are cisoriented and that the respective β-diketonates O,OЈ-chelate-bonded setting-up an octahedral surrounding at Ru II. Electrochemical (cyclic and square-wave voltammetry) and spectroelectrochemical (UV/Vis-NIR, IR) measurements were additionally carried out. Compounds 3a,b display two (3a: E 1 o Ј = 140; E 2 o Ј = 255 mV; ΔE o Ј = 115 mV for
