The employment of 3-pyridine aldoxime, (3-py)CHNOH, in Zn(II) chemistry has afforded two novel compounds: [Zn(acac)(2){(3-py)CHNOH}]·H(2)O (1·H(2)O) [where acac(-) is the pentane-2,4-dionato(-1) ion] and [Zn(2)(O(2)CMe)(4){(3-py)CHNOH}(2)] (2). Complex 1·H(2)O crystallizes in the monoclinic space group P2(1)/n. The Zn(II) ion is five-coordinated, surrounded by four oxygen atoms of two acac(-) m...

In chemical vapor deposition experiments with pulsed spray evaporation (PSE-CVD) of liquid solutions of Ni and Co acetylacetonate in ethanol as precursors, the influence of water in the feedstock on the composition and growth kinetics of deposited Ni and Co metal films was systematically studied. Varying the water concentration in the precursor solutions, beneficial as well as detrimental effec...

In the title complex, di-aqua-(1H-imidazole-κN3)(nitrato-κ2O,O')bis-(4-oxo-pent-2-en-2-olato-κ2O,O')lanthanum(III), [La(C5H7O2)2(NO3)(C3H4N2)(H2O)2], the La atom is coordinated by eight O atoms of two acetyl-acetonate (acac) anions acting as bidentate ligands, two water mol-ecule as monodentate ligands, one nitrate anions as a bidentate ligand and one N atom of an imidazolate (ImH) molecule as ...

A series of Ni(ii), Pd(ii) and Pt(ii) complexes [ML][PF6]2 [L = L1, M = Ni (1), Pd (2), Pt (3); L = L2, M = Ni (4), Pd (5), Pt (6)] and [Pt(L2)(acac)] (7) have been prepared by the reactions of two tetradentate macrocyclic amine-NHC ligand precursors, [H2L1][PF6]2 and [H2L2][PF6]2, with Ni(OAc)2·4H2O, Pd(OAc)2 and Pt(acac)2 in the presence of NaOAc. Complex 7 is isolated along with 6 from the s...

The structure of beryllium acetylacetonate, Be(acac)(2), was fully optimized at the B3LYP (using the 6-31G*, 6-311G*, and 6-311++G(3df,2p) basis sets), Hartree-Fock, and the Möller-Plesset (using the 6-31G* basis set) levels. The frequency and intensity of the vibrational bands of Be(acac)(2) and its 1,3,5-(13)C; 2,4-(13)C; 3-(2)H; 3-(2)H-2,4-(18)O derivatives were obtained at the B3LYP level u...

A series of solid solutions have been prepared by co-crystallization of Al(acac)3 and Cr(acac)3 and studied by X-ray diffraction. The end members and seven isotopic members of the series Al1 xCrx(acac)3, with x varying from 0.02 to 0.91, crystallize in the monoclinic space group P21/c with Z = 4. The unit cell parameters vary slightly with composition, and fall into the following ranges: a, 13....

Two compounds with quadruply bonded Mo2(4+) species having isonicotinate ligands bound through the carboxylate group have been designed to act as anglers by luring metal-containing Lewis acids to bind to the N-pyridyl group. The corner pieces are Mo2(DAniF)3(O2CC5H4N) and cis-Mo2(DAniF)2(O2CC5H4N)2, DAniF=N,N'-di(p-anisyl)formamidinate. The heterometallic molecular rods -Ni(acac)2-and-Rh2(O2CCH...

The title compound, [Co(C5H7O2)2(C6H12N2)] n , was obtained as a one-dimensional coordination polymer from bis-(acetyl-acetonato)di-aqua-cobalt(II), [Co(acac)2(OH2)2], and 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO), a di-amine with good bridging ability and rod-like spacer function. In the chain complex that extends along the c axis, the Co(II) atom is six-coordinated, the O-donor atoms of the ch...

The perchlorate salt of the dicationic bipy-ruthenium complex cis-[Ru(6,6'-Cl2bipy)2(H2O)2]2+ effectively catalyzes addition of beta-diketones to secondary alcohols and styrenes to yield the alpha-alkylated beta-diketones. In a catalytic addition reaction of acetylacetone to 1-phenylethanol, the kappa2-acetylacetonate complex [Ru(6,6'-Cl2bipy)2(kappa2-acac)]ClO4 was isolated after the catalysis...

Two series of heteroleptic cyclometalated platinum(II) complexes [(C(n)Oppy)Pt(acac) and (C(n)OFppy)Pt(acac)] have been prepared. Their liquid-crystal and optophysical properties were studied, in which C(n)Oppy is 2-(4-alkoxyphenyl)-5-(alkoxymethyl)pyridine and C(n)OFppy is 2-(3-fluoro-4-alkoxyphenyl)-5-(alkoxymethyl)pyridine. Only the heteroleptic cyclometalated platinum(II) complexes (n = 12 ...
