[μ-10,21-Dimethyl-3,6,14,17-tetra-za-tricyclo-[17.3.1.1]tetra-cosa-1(23),2,6,8,10,12 (24),13,17,19,21-deca-ene-23,24-diolato-κN,N,O,O:κN,N,O,O]bis-(perchlorato-κO)dimanganese(II).

ABSTRACT: In the centrosymmetric and dinuclear title complex, [Mn(2)(C(22)H(22)N(4)O(2))(ClO(4))(2)], the two Mn atoms are bridged by two phenolate O atoms of the N(4)O(2) macrocycle with an Mn⋯Mn distance of 2.9228 (11) Å. The distorted square-pyramidal N(2)O(3) coordination geometry is completed by an O atom derived from a perchlorate anion.

Project description:The dinuclear title complex, [Cu(2)(C(46)H(38)N(4)O(2))Cl(2)]·0.5C(2)H(5)OH·2H(2)O, is located on crystallographic inversion centres with two half-mol-ecules in the asymmetric unit. The two Cu(II) atoms are coordinated by a hexa-dentate dianionic ligand formed in situ from the condensation of two tridentate ligands by four imine N atoms and two bridging phenolate O atoms along with two Cl atoms at axial positions. The coordination geometry around the metal atoms is distorted square-pyramidal (? = 0.185 and 0.199). The non-bonding Cu?Cu distances are 2.9556?(12) and 2.9506?(12)?Å in the two dimers. The packing is stabilized through solvent-mediated inter-molecular O-H?O and O-H?Cl hydrogen bonds. The diamine chain of one of the dimers is disordered over two positions in a 0.680?(5):0.320?(5) ratio.

Project description:In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

10,21-Dimethyl-2,7,13,18-tetraphenyl-3,6,14,17-tetraazatricyclo[17.3.1.1]tetracosa-1(23),2,6,8(24),9,11,13,17,19,21-decaene-23,24-diol cyclohexane 0.33-solvate.

Project description:The title compound, C(46)H(40)N(4)O(2)·0.33C(6)H(12), was obtained unintentionally as a product of an attempted synthesis of a cadmium(II) complex of the [2,6-{PhSe(CH(2))(2)N=CPh}(2)C(6)H(2)(4-Me)(OH)] ligand. The full tetra-imino-diphenol macrocyclic ligand is generated by the application of an inversion centre. The macrocyclic ligand features strong intra-molecular O-H?N hydrogen bonds. The dihedral angles formed between the phenyl ring incorporated within the macrocycle and the peripheral phenyl rings are 82.99?(8) and 88.20?(8)°. The cyclo-hexane solvent mol-ecule lies about a site of [Formula: see text] symmetry. Other solvent within the lattice was disordered and was treated with the SQUEEZE routine [Spek (2009). Acta Cryst. D65, 148-155].

Project description:In the title compound, [Zn(2)(C(36)H(42)N(4)O(2))(CH(3)COO)(2)]·2CH(3)CH(2)OH, a centrosymmetric dinuclear zinc macrocyclic complex is accompanied by two half-occupied ethanol solvent molecues resulting in a 1:2 macrocycle-solvent composition. The Zn(II) atom has a square-pyramidal geometry arising from an N(2)O(3) donor set, being coordinated by two N atoms and two O atoms from the macrocyclic ligand in the equatorial sites and one O atom from an acetate anion in the apical site. The two Zn(II) atoms are linked by two phenolate O atoms, generating a four-membered Zn(2)O(2) ring at the centre of the macrocycle. The tert-butyl group shows rotational disorder over two sets of sites in a 0.552?(12):0.448?(12) ratio. In the crystal, N-H?O and O-H?O hydrogen bonds are seen and a short intra-molecular C-H?O contact occurs.

(Naphthalene-2,3-diolato-κO,O')[tris-(2-pyridyl-meth-yl)amine-κN]cobalt(III) hexa-fluoridophosphate hemihydrate.

Project description:In the title complex, [Co(C(10)H(6)O(2))(C(18)H(18)N(4))]PF(6)·0.5H(2)O, the Co(III) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from a tris-(2-pyridyl-meth-yl)amine ligand and two O atoms from a naphthalene-2,3-diolate ligand. The asymmetric unit contains two complex cations, two hexa-fluoridophosphate anions and one uncoordinated water mol-ecule. In one of the hexa-fluoridophosphate anions, four of the F aroms are disordered over two sets of sites in a 0.632 (11):0.368 (11) ratio. In the crystal, the cations, anions and water mol-ecules are connected by O-H⋯O and O-H⋯F hydrogen bonds. π-π inter-actions are present between the pyridine rings [centroid-centroid distance = 3.814 (1) Å].

trans-Tetra-kis(1-allyl-1H-imidazole-κN)bis-(thio-cyanato-κN)nickel(II).

Project description:The structure of the title compound, [Ni(NCS)(2)(C(6)H(8)N(2))(4)], consists of isolated mol-ecules of [Ni(NCS)(2)(Aim)(4)] (Aim = 1-allyl-imidazole), which contain a distorted octa-hedral NiN(6) chromophore. The NCS(-) anions are trans and four N atoms from the 1-allyl-imidazole ligands define the equatorial plane. The mean Mn-N(Aim) and Mn-N(NCS) distances are 2.105 (2) and 2.098 (2) Å, respectively. Weak C-H⋯N inter-actions contribute to the crystal packing stability.

Tetra-aqua-bis-(pyridine-κN)nickel(II) dinitrate.

Project description:In the title compound, [Ni(C(5)H(5)N)(2)(H(2)O)(4)](NO(3))(2), the Ni(II) ion is coordinated by two N-bonded pyridine ligands and four water mol-ecules in an octa-hedral coordination mode. The asymmetric unit consists of one Ni(II) ion located on an inversion center, as well as one pyridine ligand, one nitrate anion and two water mol-ecules in general positions. In the crystal structure, the discrete complex cations and nitrate anions are connected by O-H⋯O and C-H⋯O hydrogen bonds.

trans-(5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene-κN,N',N'',N''')bis-(nitrito-κN)cobalt(III) perchlorate hemihydrate.

Project description:The asymmetric unit of the title Co(III) complex, [Co(NO(2))(2)(C(16)H(32)N(4))]ClO(4)·0.5H(2)O, comprises two complex cations, two perchlorate anions and a water mol-ecule of crystallization. The Co(III) atoms exist within distorted octa-hedral N(6) geometries defined by four N atoms of the macrocycle ligand and trans-N atoms derived from the nitrite anions. Systematic variations in the Co-N bond lengths are correlated with the presence of intra-molecular N-H⋯O(nitrite) hydrogen bonds. In the crystal, water-O-H⋯O(perchlorate) hydrogen bonds, involving one of the independent perchlorate anions only, lead to supra-molecular chains along the b-axis direction. The three-dimensional architecture is consolidated by numerous C-H⋯O inter-actions. The crystal studied was a non-merohedral, racemic twin.

Project description:In the title compound, [Ni(C(8)H(4)O(4))(C(36)H(44)N(4)O(4))](n), the Ni(II) atom is coordinated in a distorted octa-hedral geometry by the four N atoms of the 1,12,15,26-tetra-aza-5,8,19,22-tetra-oxa-3,4:9,10:17,18:23,24-tetra-benzocyclo-octa-cosane ligand and two O atoms from the terephthalate dianions. The Ni(II) atoms, which lie on inversion centres, are linked via terephthalate ligands to form a chain structure along [101]. The structure is stabilized by three intra-molecular and one inter-molecular N-H?O hydrogen bonds.
