Aqua-(5,10,15,20-tetra-phenyl-porphyrin-ato-?(4) N)cadmium(II)-18-crown-6 (1/1).

ABSTRACT: The title compound, [Cd(C44H28N4)(H2O)]·(C12H24O6), was made by the reaction of the [Cd(TPP)] with an excess of 18-crown-6 in chloro-benzene (where TPP is tetra-phenyl-porphyrinate). The Cd(II) cation is chelated by a TPP anion and coordinated by a water mol-ecule in a distorted N4O square-pyramidal geometry, the Cd(II) cation being displaced by 0.7533?(9)?Å from the mean plane of four N atoms of TPP anion. The porphyrin core presents a significant distortion, the maximum atomic deviation from the 24-atom mean plane is 0.1517?(2)?Å. The 18-crown-6 mol-ecule is linked with the Cd(II) complex via classical O-H?O hydrogen bonds. In the crystal, weak C-H?? inter-actions link the complex and 18-crown-6 mol-ecules into a three-dimensional supra-molecular architecture.

Project description:In the title compound, [Zn(C44H28N4)]·C12H24O6, the Zn(II) ion lies on an inversion center and the asymmetric unit contains one half of a Zn(TPP) complex (TPP = 5,10,15,20-tetra-phenyl-porphyrin dianion) and one half of a centrosymmetric 18-crown-6 mol-ecule.

[5,10,15,20-Tetra-kis-(penta-fluoro-phen-yl)porphyrin-ato]zinc(II) benzene disolvate.

Project description:Single crystals of the title zinc porphyrinato complex, [Zn(C44H8F20N4)]·2C6H6, were obtained by the solvent evaporation method. The molecular complex exhibits point group symmetry with the central ZnII atom located on an inversion centre. The porphyrinato core is approximately planar, and the cation has no other ligating atoms than the four porphyrinato N atoms. π-π inter-actions between benzene solvent mol-ecules and [Zn(TFPP)] units lead to multilayer packing structures. In addition, inter-molecular C-H⋯F hydrogen bonding is observed between [Zn(TFPP)] mol-ecules.

Diaqua-(5,10,15,20-tetra-phenyl-porphyrinato-κ(4)N)magnesium-18-crown-6 (1/1).

Project description:In the title compound, [Mg(C(44)H(28)N(4))(H(2)O)(2)]·C(12)H(24)O(6), the Mg(II) cation lies on an inversion center and is octa-hedrally coordinated by the four N atoms of the deprotonated tetra-phenyl-porphyrin (TPP) ligand and by two water mol-ecules. The asymmetric unit contains one half of the [Mg(TPP)(H(2)O)(2)] complex and one half of an 18-crown-6 mol-ecule. The average equatorial magnesium-pyrrole N atom distance (Mg-N(p)) is 2.071 (1) Å and the axial Mg-O(H(2)O) bond length is 2.213 (1) Å. The crystal packing is stabilized by two O-H⋯O hydrogen bonds between coordinating water mol-ecules and adjacent 18-crown-6 mol-ecules, and exhibits a one-dimensional supramolecular structure along the a axis. The supramolecular architecture is futher stabilized by weak C-H⋯π inter-actions. The 18-crown-6 mol-ecule is disordered over two sets of sites with an occupancy ratio of 0.8:0.2.

Project description:In the title compound, [Cd(C(12)H(16)NO(4)S)(2)(H(2)O)]·2H(2)O, the Cd atom is located on a twofold rotation axis and a distorted CdO(8) dodeca-hedral arrangement arises from the coordination of the two chelating ligands and four water mol-ecules. A network of N-H?O, O-H?O and C-H?O hydrogen bonds help to establish the crystal packing. Both coordinated and uncoordinated water molecules are disordered with an approximate half-occupation for each of the water molecules.

catena-Poly[[[aqua-cadmium(II)]bis-(?-4-hydroxy-pyridine-2,6-dicarboxyl-ato)[aqua-cadmium(II)]di-?-aqua] tetra-hydrate].

Project description:The title polymeric compound, {[Cd(2)(C(7)H(3)NO(5))(2)(H(2)O)(4)]·4H(2)O}(n) or {[Cd(2)(hypydc)(2)(H(2)O)(4)]·4H(2)O}(n) (where hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of cadmium(II) nitrate hexa-hydrate with 4-hydroxy-pyridine-2,6-dicarboxylic acid and propane-1,3-diamine, in a 1:2:2 molar ratio in aqueous solution. The compound is a seven-coordinate binuclear polymeric complex with distorted penta-gonal bipyramidal geometry around Cd(II) [Cd-O = 2.247?(4)-2.474?(3)?Å]. In the binuclear monomeric units, the central atoms join together by O atoms of two bridging tridentate (hypydc)(2-) ligands, and the polymer propagates via two bridging water mol-ecules that link each Cd(II )centre of one monomer to the adjacent neighbour. Propane-1,3-diamine (pn) does not appear in the product but plays a role as a base. Inter-molecular O-H?O and C-H?O hydrogen bonds, and ?-? stacking inter-actions, with distances of 3.725?(3) and 3.766?(3)?Å, connect the various components.

Crystal structure of di-aqua-[5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinato-?(4) N]iron(III) di-aqua-(18-crown-6)potassium bis-(tri-fluoro-methane-sulfonate)-18-crown-6 (1/2).

Project description:In the title compound, [Fe(III)(C48H36N4O2)(H2O)2][K(C12H24O6)(H2O)2](SO3CF3)2·2C12H24O6, the Fe(III) atom is situated on an inversion centre and is octa-hedrally coordin-ated by four pyrrole N atoms of the deprotenated 5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinate ligand and two water mol-ecules. The average equatorial Fe-N(pyrrole) bond length [2.043?(6)?Å] is consistent with a high-spin (S = 5/2) iron(III) metalloporphyrin derivative. The K(+) cation, which also lies on an inversion centre, is chelated by the six O atoms of one 18-crown-6 mol-ecule and is additionally coordinated by two water mol-ecules in a distorted hexa-gonal-bipyramidal geometry. In the crystal, the cations, anions and one non-coordinating 18-crown-6 mol-ecule are linked by classical O-H?O hydrogen bonds and non-conventional C-H?O hydrogen bonds, leading to a one-dimensional supra-molecular architecture along [10-1]. The crystal packing is further stabilized by weak C-H?? inter-actions involving pyrrole and phenyl rings of the porphyrins, as well as weak C-H?F contacts involving the (SO3CF3)(-) counter-ion and the 18-crown-6 mol-ecules.

μ-Pyrazine-bis-[tetra-aqua-cadmium(II)] μ-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H⋯O inter-actions.

Aqua-(4-cyano-pyridine-?N (4))(5,10,15,20-tetra-phenyl-porphyrinato-?(4) N)magnesium.

Project description:In the title complex, [Mg(C44H28N4)(C6H4N2)(H2O)], the Mg(2+) cation is octa-hedrally coordinated and lies on an inversion center with the axially located 4-cyano-pyridine and aqua ligands exhibiting 50% substitutional disorder. The cyano-bound 4-cyano-pyridine mol-ecule also is disordered across the inversion centre. The four N atoms of the pyrrole rings of the dianionic 5,10,15,20-tetra-phenyl-porphyrin ligand occupy the equatorial sites of the octa-hedron [Mg-N = 2.0552?(10) and 2.0678?(11)?Å] and the axial Mg-(N,O) bond length is 2.3798?(12)?Å. The crystal packing is stabilized by weak inter-molecular C-H?? inter-actions.

(5,10,15,20-Tetra-phenyl-porphyrinato-?N)(2,2,2-trifluoro-1-phenyl-ethyl-idene-?C)ruthenium(II): a stable fluorinated alkyl-idene complex of a ruthenium(II) porphyrin.

Project description:In the title compound, [Ru(C(44)H(28)N(4))(C(8)H(5)F(3))], the fluorin-ated alkyl-idene group is bound to a five-coordinate Ru atom, which is located toward the carbene C atom, 0.3301?(5)Å from the least-squares plane of the C(20)N(4) porphyrin core. The Ru=C bond is tilted slightly from the normal to the C(20)N(4) least-squares plane due to steric repulsion between the porphyrinate ligand and the bulky trifluoro-methyl group. The Ru=C bond length of 1.838?(2)?Å is comparable with those in bis-(subsituted phen-yl)carbene analogs.
