Project description:In the centrosymmetric tetra-nuclear title complex, [Ni(4)(C(12)H(15)NO(3))(2)(CH(3)COO)(2)(N(3))(2)(CH(3)OH)(2)]·2CH(3)OH, the asymmetric unit comprises half of a complex mol-ecule and a methanol solvent mol-ecule. The Ni(II) ions display two different coordination environments: (i) two O atoms from the Schiff base ligand, two O atoms from symmetry-related methanol mol-ecules and an O atom from an acetate group, one N atom from the azide group, and (ii) two O atoms and one N atom from the Schiff base, one O atom from methanol, one O atom from the acetate anion, and one N atom from the azide group. Four coplanar Ni(II) ions are connected by two μ(2)-bridging O atoms from the two deprotonated Schiff bases, two μ(3)-O atoms from methanol mol-ecules, two μ(1,1)-N atoms from two azide ions, and four O atoms from acetate groups. The shortest Ni⋯Ni distance in the tetra-nuclear unit is 2.962 (2) Å. O-H⋯O hydrogen bonds between the methanol solvent mol-ecule and an acetate O atom feature in the crystal packing.
Project description:The structure of the title complex, [RuCl2(C6H6NO)4], exhibits point group symmetry . The structure exhibits disorder around a axis. The 4-meth-oxy-pyridine ligands have a propeller-like arrangement around the RuII atom at 52.0 (3)° from the RuN4 plane.
Project description:In title compound, C(8)H(8)F(3)NO, the meth-oxy group is inclined at 8.7 (4)° to the benzene ring plane. The crystal structure is stabilized by inter-molecular N-H⋯F, N-H⋯N and C-H⋯F hydrogen-bonding inter-actions.
Project description:In the mol-ecule of the title compound, C(13)H(13)NO, the two benzene rings are oriented at a dihedral angle of 59.9 (2)°. In the crystal structure, the benzene rings of neighbouring mol-ecules are oriented nearly parallel or perpendicular, making dihedral angles of 2.8 (2) and 79.5 (2)°, respectively. The crystal structure is stabilized by a network of C-H⋯π and N-H⋯π inter-actions.
Project description:In the title compound, [Zn(C48H36N4O4)]·2CH2Cl2, the Zn(II) ion lies on an inversion center and is coordinated in an almost ideal square-planar geometry. The asymmetric unit also contains one di-chloro-methane solvent mol-ecule. The unique meth-oxy-substituted benzene rings form dihedral angles of 59.38 (6) and 66.77 (6)° with the mean plane (r.m.s. deviation of fitted atoms = 0.0282 Å) of the atoms in the porphyrin core. The packing is characterized by close contacts between the Zn(II) ion and two symmetry-related mol-ecules through the O atoms of a meth-oxy-phenyl group [Zn⋯O = 2.694 (2) Å], forming a two-dimensional network parallel to (100).
Project description:The title compound, [Ni(C(40)H(28)N(4)O)], was obtained from a Grignard reaction of the respective formyl-porphyrin to yield {5-[hy-droxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II), followed by crystallization from methyl-ene chloride/methanol. The mol-ecule exhibits a ruffled macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (Δ24) of 0.26 Å and an average Ni-N bond length of 1.931 (2) Å. In line with the asymmetrical substituent pattern, the degree of distortion is slightly larger at point of attachment of the meth-oxy(phen-yl)methyl residue than at the unsubstituted meso position. The meth-oxy group attached to the chiral C atom is disordered in a 0.534 (4):0.466 (4) ratio.
Project description:The title compound, C(76)H(80)O(16), is a macrocyclic structure. This novel resorcin[4]arene derivative has (meth-oxy-carbon-yl)meth-oxy 'head' groups on the upper rim. The compound has a C(2v) 'boat' geometry and there are a range of C-H⋯O contacts in the crystal structure.
Project description:The centrosymmetric binuclear Cu(II) title complex, [Cu(2)(C(8)H(7)O(3))(4)(CH(3)CN)(2)], has a paddle-wheel-type structure [Cu-Cu distance = 2.6433 (3) Å]. Each Cu(II) ion is coordin-ated by four O atoms from two 3-meth-oxy-benzoate ligands and one acetonitrile N atom in a square-pyramidal geometry.
Project description:The asymmetric unit of the mononuclear title complex, [NiBr2(C3H8O)4], comprises a Ni(II) cation located on a centre of inversion, one Br(-) anion and two propan-2-ol ligands. The Ni(II) cation exhibits a distorted trans-Br2O4 environment. There are O-H⋯Br hydrogen bonds connecting neighbouring mol-ecules into rows along [100]. These rows are arranged in a distorted hexa-gonal packing and are held together by van der Waals forces only.
Project description:The asymmetric unit of the title nickel(II) porphyrin, [Ni(C48H60N4O2)], contains one independent mol-ecule. The average Ni-N bond length is 1.917 (13) Å. The mol-ecules are arranged in a closely spaced lattice structure in which neighbouring porphyrins are oriented in inversion-related dimers. The nickel(II) porphyrin is characterized by a significant degree of a ruffled (B 1u ) conformation with small contributions from saddle (B 2u ) and wave (y) [Eg (y)], as determined using normal structural decomposition. Disorder in the 2,5-di--meth-oxy-phenyl substituent was modelled over two positions with a 60% occupancy for the major moiety. One of the ethyl groups is also disordered over two positions and was modelled with the major moiety being present in 51.3% occupancy.
