(2-Hydroxy-phenyl-imido-?N)(methano-lato-?O)[2-(2-oxidobenzyl-ideneamino)phenolato-?O,N,O'](triphenyl-phosphine-?P)rhenium(V).

ABSTRACT: In the neutral title compound, [Re(C(6)H(5)NO)(C(13)H(9)NO(2))(CH(3)O)(C(18)H(15)P)], an 18-valence-electron complex, the Re(V) ion lies in an octa-hedral coordination geometry with the tridentate dianionic Schiff base 2-(2-oxidobenzyl-idene-amino)phenolate ligand occupying three equatorial coordination sites, and with the triphenyl-phosphine ligand situated trans to the imine N atom. The Re(V) coordination is completed with a methano-late ligand and a 2-hydroxy-phenyl-imido(2-) ligand. There are two molecules in the asymmetric unit. The crystal structure involves O-H?O and C-H?O hydrogen bonds. One N and one C atom are disordered over two positions; the site occupancy factors are ca 0.7 and 0.3.

Tetra-μ(3)-methano-lato-tetra-kis-[(2-formyl-6-meth-oxy-phenolato)methano-lnickel(II)].

Project description:The molecule of the title compound, [Ni(4)(CH(3)O)(4)(C(8)H(7)O(3))(4)(CH(3)OH)(4)], has S(4) symmetry. Each of the four Ni(II) atoms occupies every other corner of a cube, with the alternate corners occupied by μ(3)-methano-late bridging groups linking to three Ni(II) atoms. Each Ni(II) atom is in an O(6) octa-hedral coordination environment formed by three O atoms from three μ(3)-methano-late groups, one from methanol, and two others from a bidentate 2-formyl-6-meth-oxy-phenolate ligand. The Ni-O bond distances range from 2.0020 (14) to 2.0938 (14) Å, the cis bond angles range from 81.74 (6) to 97.63°, and the trans bond angles range from 168.76 (5) to 175.22 (6)°. There are bifurcated hydrogen-bonding inter-actions between the coordinated methanol OH groups and both the phenolic and meth-oxy O atoms of an adjoining 2-formyl-6-meth-oxy-phenolate moiety. In addition, there are weak inter-molecular C-H⋯O inter-actions involving the meth-oxy O atoms.

(?-2,3-Dibromo-succinato-?O:O)bis-[methano-lato-?O)triphenyl-anti-mony(V)].

Project description:In the title mol-ecule, [Sb(2)(C(6)H(5))(6)(C(4)H(4)Br(2)O(4))(CH(3)O)(2)], two [Sb(CH(3)O)Ph(3)](+) units are linked by the two carboxyl-ate O atoms of a meso-2,3-dibromo-succinate bridging ligand, forming a dinuclear compound. The Sb(IV) atom is five-coordinated in a slightly distorted trigonal-bipyramid geometry by phenyl C atoms in the equatorial positions and two O atoms in the axial positions. C-H?O inter-actions link the mol-ecules into a two-dimensional network parallel to (010). The -CH- group of the centrosymmetric 2,3-dibromosuccinate anion is disordered over two sites in a 0.6:0.4 ratio.

Rhenium-Imido Corroles.

Project description:Metallocorroles involving 5d transition metals are currently of interest as near-IR phosphors and as photosensitizers for oxygen sensing and photodynamic therapy. Their syntheses, however, are often bedeviled by capricious and low-yielding protocols. Against this backdrop, we describe rhenium-imido corroles, a new class of 5d metallocorroles, synthesized simply and in respectable (∼30%) yields via the interaction of a free-base corrole, Re2(CO)10, K2CO3, and aniline in 1,2,4-trichlorobenzene at ∼190 °C in a sealed vial under strict anaerobic conditions. The generality of the method was shown by the synthesis of six derivatives, including those derived from meso-tris(pentafluorophenyl)corrole, H3[TPFPC], and five different meso-tris(p-X-phenyl)corroles, H3[TpXPC], where X = CF3, F, H, CH3, OCH3. Single-crystal X-ray structures obtained for two of the complexes, Re[TpFPC](NPh) and Re[TpCF3PC](NPh), revealed relatively unstrained equatorial Re-N distances of ∼2.00 Å, a ∼ 0.7-Å displacement of the Re from the mean plane of the corrole nitrogens, and an Re-Nimido distance of ∼1.72 Å. Details of the corrole skeletal bond distances, diamagnetic 1H NMR spectra, relatively substituent-independent Soret maxima, and electrochemical HOMO-LUMO gaps of ∼2.2 V all indicated an innocent corrole macrocycle. Surprisingly, unlike several other classes of 5d metallocorroles, the Re-imido complexes proved nonemissive in solution at room temperature and also failed to sensitize singlet oxygen formation, indicating rapid radiationless deactivation of the triplet state, presumably via the rapidly rotating axial phenyl group. By analogy with other metal-oxo and -imido corroles, we remain hopeful that the Re-imido group will prove amenable to further elaboration and thereby contribute to the development of a somewhat challenging area of coordination chemistry.

[N'-(3-Eth-oxy-2-oxidobenzyl-idene-κO)-4-methyl-benzohydrazidato-κO,N'](methano-lato-κO)oxidovanadium(V).

Project description:The title oxidovanadium(V) complex, [V(C(17)H(16)N(2)O(3))(CH(3)O)O], was obtained by the reaction of 3-eth-oxy-2-hy-droxy-benzaldehyde, 4-methyl-benzohydrazide and vanadyl sulfate in methanol. The V(V) atom is coordinated by the O,N,O'-tridentate Schiff base ligand, one methano-late O atom and one oxide O atom, forming a distorted VO(4)N square-pyramidal coordination geometry. The oxide O atom lies at the apex of the square pyramid and the N atom of the ligand and the methano-late O atom are trans. The dihedral angle between the benzene rings of the ligand is 1.8 (3)°.

Project description:In the crystal structure of the title compound, [Sn(CH(3))(2)(C(9)H(8)N(2)O(3))(C(10)H(8)N(2))], the Sn atom exhibits a penta-gonal bipyramidal coordination geometry defined by two C, three N and two O atoms. The bond distances for Sn-C, Sn-N and Sn-O are in the ranges 2.097 (3)-2.098 (3), 2.298 (2)-2.623 (2) and 2.157 (2)-2.266 (2) Å, respectively. The mol-ecular structure of the monomeric compound is stabilized by three intra-molecular C-H⋯O hydrogen bonds, all involving bipyridine C-H groups.

[N'-(5-Bromo-2-oxidobenzyl-idene-?O)-2-chloro-benzohydrazidato-?N',O](methanol-?O)(methano-lato-?O)oxido-vanadium(V).

Project description:The V(V) atom in the title complex, [V(C(14)H(8)BrClN(2)O(2))(CH(3)O)O(CH(3)OH)], is six-coordinated by one phenolate O, one imine N and one enolic O atom of the hydrazone ligand, one oxide O atom, one methanol O atom and one methoxide O atom in a distorted octa-hedral geometry.

The deviation of the V atom towards the oxide O atom from the plane defined by the three donor atoms of the hydrazone ligand and the meth-oxy O atom is 0.318?(2)?Å. Bond lengths are comparable with those observed in similar oxidovanadium(V) complexes with hydrazone ligands. In the crystal, pairs of mol-ecules are linked through inter-molecular O-H?N hydrogen bonds, forming dimers.
