Tris[tris-(1,10-phenanthroline-?N,N')iron(II)] dodeca-tungstoferrate dihydrate.

ABSTRACT: The title compound, [Fe(C(12)H(8)N(2))(3)](3)[FeW(12)O(40)]·2H(2)O, was prepared under hydro-thermal conditions. The discrete Keggin-type [FeW(12)O(40)](6-) heteropolyoxoanion has threefold symmetry, with the Fe(II) atom located on the threefold rotation axis. The central FeO(4) tetra-hedron in the anion shares its O atoms with four W(3)O(13) trinuclear units, each of which is made up of three edge-shared WO(6) octa-hedral units. The Fe(II) atom in the complex cation, viz [Fe(phen)(3)](2+) (phen is 1,10-phen-anthroline), shows a slightly distorted octa-hedral geometry defined by six N atoms from three phen ligands. The polyoxoanions pack together with the cations, with the disordered water mol-ecules located in voids; the site occupancy factor for each water O atom is 0.33.

Project description:The title compound, [Fe(C14H12N2)3](C4N3)2, consists of one [Fe(dimephen)3](2+) complex cation (dimephen = 5,6-dimethyl-1,10-phenanthroline) and two uncoordinating tcm anions (tcm = tricyano-methanide). In the complex cation, the Fe(II) atom is coordinated by six N atoms from three chelating dimephen ligands at an average Fe-N distance of 1.963?(4)?Å giving a distorted octa-hedral geometry. The crystal structure is stabilized by weak C-H?N hydrogen bonds and C N?? inter-actions between planar [maximum deviations of 0.024?(3) and 0.015?(3)?Å] tcm anions and pyridine rings of dimephen [N2?centroid = 3.531?(3) and 3.726?(3)?Å; C N?centroid = 96.4?(2) and 97.1?(2)°].

Project description:In the title salt, [Fe(C(12)H(8)N(2))(3)][Fe(2)Cl(6)O], the ionic components are linked into a two-dimensional supra-molecular layer by two pairs of C-H?Cl hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.655?(4) and 3.498?(3)?Å]. The salt is characterized as a mixed-valent Fe(II)-Fe(III) compound, in which an Fe(II) atom is coordinated by three phen ligands, forming a six-coordinated cationic entity and the anionic part is formed by two Fe(III) atoms in tetra-hedral coordination environments constructed by three chloride ions and one bridging oxide ligand. Intra-molecular C-H?N hydrogen bonds are observed.

Project description:Single crystals of the title heterometallic compound, [Fe(C(12)H(8)N(2))(3)][Cr(NCS)(4)(C(12)H(8)N(2))](2)·3CH(3)CN·H(2)O or [Fe(Cphen)(3)][Cr(NCS)(4)(phen)](2)·3CH(3)CN·H(2)O, were pre-pared using the one-pot open-air reaction of iron powder, Reineckes salt and 1,10-phenanthroline (phen) in acetonitrile. The asymetric unit consists of an [Fe(phen)(3)](2+) cation, two [Cr(phen)(NCS)(4)](-) anions, three acetonitrile solvent mol-ecules and a water mol-ecule. The Fe and Cr atoms both show a slightly distorted octa-hedral FeN(6) and CrN(6) coordination geometry with adjacent angles in the range 79.67?(12)-95.21?(12)°.

(Acetyl-acetonato)(dicyanamido)(1,10-phenanthroline)copper(II) dihydrate.

Project description:In the title compound, [Cu(C(5)H(7)O(2))(C(2)N(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is five-coordinated in a square-pyramidal geometry with two acetyl-acetonate O and two phenanthroline N atoms forming the base. The apical position is occupied by the central N atom of the dicyanamide ligand. The dicyanamide N atoms are each involved in hydrogen bonds to water mol-ecules. There are also hydrogen bonds between both the water mol-ecules and their centrosymmetric pairs, creating a hydrogen-bonded chain along the b-axis direction.

Project description:The asymmetric unit of the title compound, [Ni(C(12)H(8)N(2))(3)][Cr(2)O(7)]·4H(2)O, contains one cation, one anion and four water mol-ecules, three of which are disordered over two sites with equal occupancies.

Project description:The asymmetric unit of the title compound, {[Mn3{W(CN)8}2(C16H16N2)3(C3H7NO)3(CH3OH)3]·2H2O} n , consists of three [Mn(N,N-di-methyl-formamide)(methanol)(3,4,7,8-tetra-methyl-1,10-phenanthroline)](2+) cations, two [W(CN)8](3-) anions and two water mol-ecules. Each water mol-ecule is disordered over three sets of sites, with a refined occupancy ratio of 0.310?(9):0.275?(9):0.415?(9) for one mol-ecule and 0.335?(9):0.288?(9):0.377?(9) for the other mol-ecule. The Mn(II) atoms exhibit a distorted octa-hedral geometry, while the W(V) atoms adopt a distorted square-anti-prismatic geometry. The Mn(II) and W(V) atoms are linked alternatively through cyanide groups, forming a tetra-nuclear 12-atom rhombic metallacycle. Adjacent metallacycles are further connected by ?2-bridging cyanide anions, generating a 3,2-chain structure running parallel to [101]. Inter-chain ?-? inter-actions are observed [centroid-centroid distances = 3.763?(3) and 3.620?(2)?Å].

Bis[tris-(1,10-phenanthroline)nickel(II)] tris-[dicyanidoargentate(I)] nitrate 4.2-hydrate.

Project description:The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H?O and C-H?N inter-actions may help to establish the packing.

Tetra-aqua-(1,10-phenanthroline-?N,N')cadmium(II) sulfate dihydrate.

Project description:In the title mononuclear complex, [Cd(C(12)H(8)N(2))(H(2)O)(4)]SO(4)·2H(2)O, the coordination geometry around the Cd(II) atom is a distorted octa-hedron, with two aqua ligands occupying the axial positions. Inter-molecular O-H?O hydrogen bonds lead to the formation of a two-dimensional layer structure parallel to (001). The layers are connected by ?-? inter-actions between the pyridyl and benzene rings of the phenanthroline ligands [centroid-centroid distances = 3.591?(1) and 3.610?(1)?Å].

Tris(1,10-phenanthroline-?N,N')nickel(II) dinitrate tetra-hydrate.

Project description:In the title complex, [Ni(C(12)H(8)N(2))(3)](NO(3))(2)·4H(2)O, the Ni(II) ion is octa-hedrally coordinated by three bidentate 1,10-phenanthroline ligands, each forming a five-membered chelate ring. In the crystal, O-H?O and C-H?O hydrogen bonds are present between the complex cations, nitrate anions and water mol-ecules. O-H?O hydrogen bonds between the uncoord-inated water mol-ecules lead to the formation of a four-membered ring water cluster, with a planar configuration. There were an additional five grossly disordered water mol-ecules in the asymmetric unit, which were removed by the subroutine SQUEEZE; these were were excluded in the calculation of the molecular weight, etc. ?-? stacking inter-actions between the aromatic rings are also observed [centroid-centroid distances = 3.697?(2), 3.728?(2) and 3.761?(2)?Å].
