Crystal structure of dichlorido-1?Cl,2?Cl-(?2-3,5-dimethyl-1H-pyrazolato-1?N2:2?N1)(3,5-dimethyl-1H-pyrazole-2?N2){?-2-[(2-hydroxyethyl)amino-1?2N,O]ethanolato-1:2?2O:O}dicopper(II)

ABSTRACT: The title pyrazolate aminoalcohol complex comprises two dimethylpyrazole molecules in monodentate and bidentate-bridged coordination modes and a monodeprotonated diethanolamine molecule. The title compound, [Cu2(C5H7N2)(C4H10NO2)Cl2(C5H8N2)], is a pyrazolate aminoalcohol complex which contains two dimethylpyrazole molecules in monodentate and bidentate-bridged coordination modes and a monodeprotonated diethanolamine molecule. Both copper atoms are involved in the formation of non-planar five-membered chelate rings. One Cu atom is in a distorted tetrahedral environment formed by the pyridine nitrogen atom of the protonated dimethylpyrazole molecule, the N atom of the deprotonated bridged dimethylpyrazole, the Cl atom and the bridged O atom of the monodeprotonated diethanolamine. The second Cu atom has an intermediate environment between trigonal bipyramidal and square pyramidal, formed by the N atom of the deprotonated bridged dimethylpyrazole, the Cl atom and the N atom of the aminoalcohol, and two O atoms of the deprotonated and protonated OH groups. In the crystal, N—H?Cl hydrogen bonds link the molecules into antisymmetric chains running along the a-axis direction. Adjacent chains are connected by O—H?O hydrogen bonds involving the hydroxyl group as donor.

Project description:The title compound, [Hg2Cl4(C26H54B10P2)], was synthesized by the reaction of 1,2-bis-(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with HgCl2. Both Hg(II) atoms show a distorted tetra-hedral coordination geometry, provided by the two bridging chloride anions and the P atoms of the diphosphanyl ligand for one metal atom, and by two bridging and two terminal chloride anions for the other. The five-membered HgP2C2 chelate ring assumes an envelope conformation, with the Hg(II) atom displaced by 0.1650 (5) Å from the mean plane of the other four atoms (r.m.s. deviation = 0.002 Å). In the crystal, B-H⋯Cl interactions link the molecules, forming a supramolecular chain along the a-axis direction.

Crystal structure of bis-{μ-2-[bis-(2-hy-droxy-eth-yl)amino]-ethano-lato}bis-(μ-3,5-di-methyl-pyrazolato)tricopper(II) dibromide sesquihydrate.

Project description:In the title bicyclic trinuclear pyrazolate amino-alcohol complex, [Cu3(C5H7N2)2(C6H14NO3)2]Br2·1.5H2O, the central Cu atom lies on a center of symmetry and is involved in the formation of two five-membered rings. It has a coordination number of 4, is in a distorted tetra-hedral environment and is connected by the bridging oxygen atoms of the deprotonated OH groups of different amino-alcohol groups, and by the N atoms of deprotonated di-methyl-pyrazole ligands. The peripheral Cu atom is in a trigonal-bipyramidal coordination environment formed by the nitro-gen atom of the deprotonated bridging di-methyl-pyrazole unit, the bridging oxygen atom of the deprotonated OH group, two oxygen atoms of the protonated hy-droxy groups and the nitro-gen atom of tri-ethano-lamine. One of the C atoms and the Br- anion were found to be disordered over two positions with occupancy factors of 0.808 (9):0.192 (9) and 0.922 (3):0.078 (3), respectively.

Project description:The reaction of Cp(CO)2FeI with 2-ethynyl-pyridine under Sonogashira conditions [5% PdCl2(PPh3)2, 10% CuI, THF-NEt3 (2:1)] afforded the title binuclear μ-pyridyl-vinyl-idene FePd complex (FePd1) as a benzene solvate, [FePd(C5H5)(C7H5N)I(CO)2]·C6H6, in a very low yield rather than the expected iron o-pyridyl-ethynyl complex Cp(CO)2Fe-C≡C-(2-C5H4N). The Fe and Pd atoms in FePd1 are bridged by carbonyl and pyridyl-vinyl-idene ligands, the pyridyl N atom being bonded to the palladium atom. The use of equimolar amounts of PdCl2 increases the yield of FePd1 to 12%. The reaction pathway leading to FePd1 is proposed.

Bis(μ4-adamantane-1,3-di-carboxyl-ato-1κO 1:2κO 1':3κO 3:4κO 3')octa-carbonyl-1κ2 C,2κ2 C,3κ2 C,4κ2 C-tetra-kis-[tris-(4-methyl-phen-yl)phosphane]-1κP,2κP,3κP,4κP-tetra-osmium(I)(2 Os-Os).

Project description:The title complex, [{Os2(CO)4(C21H21P)2}2(C12H14O4)2], is a centrosymmetric mol-ecular loop consisting of two Os-Os sawhorse units linked by two adamantane di-carboxyl-ato bridges. It was synthesized by the microwave-mediated reaction between Os3(CO)12 and adamantane-1,3-di-carb-oxy-lic acid. In contrast to the related complex [{Os2(CO)6}2(μ4-adamantane-1,3-di-acetate)2], the metal-metal axes within each mol-ecule are oriented parallel rather than perpendicular to one another. The crystal structure exhibits cavities that contain residual electron density peaks, but it was not possible to unambiguously identify the solvent therein. The contribution of the disordered solvent mol-ecules to the scattering was removed using the SQUEEZE (Spek (2015 ▸). Acta Cryst. C71, 9-18) routine in PLATON [Spek (2020 ▸). Acta Cryst. E76, 1-11]. These solvent mol-ecules are not considered in the given chemical formula and other crystal data.

Project description:Partial hydrolysis of a sample of [Mg(dme)3][Al(hfip)4]2 crystals led to the formation of the title complex, [Mg(dme)2{HOAl(hfip)2OAl(hfip)3}] (dme = di-meth-oxy-ethane and hfipH = hexa-fluoro-iso-propanol) or [Mg(C4H10O2)2O(OH)Al2(C3HF6O)5]. The magnesium cation exhibits a distorted octa-hedral coordination with two bidentate di-meth-oxy-ethane mol-ecules and a dinuclear aluminate anion, coordinated to Mg2+ via oxido and hydroxido units. The anion is an oxido-bridged species, [HOAl(hfip)2(μ-O)Al(hfip)3]2-, with one Al3+ cation tetra-hedrally coordinated by an oxido (O2-) anion, a hydroxido anion, and two hfip groups, whereas the second Al3+ cation is coordinated by the oxido anion and three hfip groups.

Crystal structure of μ6-chlorido-nona-kis-(μ-4-chloro-pyrazolato)bis-μ3-methoxo-hexa-copper(II).

Project description:The hexa-nuclear title compound, [{Cu3(μ3-OCH3)(μ-C3H2ClN2)3}2(μ-C3H2ClN2)3(μ6-Cl)] or [Cu6(C3H2ClN2)9(CH3O)2Cl], crystallizes in the space group Pbcn, with individual mol-ecules being located on a twofold rotation axis. The mol-ecule adopts a trigonal prismatic shape, with two trinuclear units linked by three 4-chloro-pyrazolate ligand bridges by encapsulating a Cl- anion in a μ6-coordination mode. In the crystal, individual mol-ecules are stacked into rods parallel to [1-10] that are arranged in a pseudo-hexa-gonal packing. Cohesion between mol-ecules is accomplished through weak C-H⋯Cl inter-actions.

Project description:In the title dinuclear complex, [Cu(2)(C(5)H(6)BrN(2))Cl(3)(C(5)H(7)BrN(2))(4)]·CH(3)CN, both Cu(II) ions are in slightly distorted square-pyramidal coordination geometries. The basal planes are defined by three N atoms from three 4-bromo-3,5-dimethyl-pyrazolate ligands, one of which is bridging, and one Cl ligand. A bridging Cl ligand forms the apical site for both Cu(II) ions. In the crystal, N-H?Cl hydrogen bonds connect complex mol-ecules into chains along [100]. Intra-molecular N-H?Cl hydrogen bonds are also observed.
