Bis[N'-(9H-fluoren-9-yl-idene)benzohydrazidato-κN',O]copper(II).

ABSTRACT: In the title complex, [Cu(C(20)H(13)N(2)O)(2)], the Cu(II) ion is tetra-coordinated by an N(2)O(2) set of two ligands in a distorted recta-ngular-planar geometry. The dihedral angle between the two coordinated five-membered metalla rings is 37.5 (3)°. The mol-ecular configuration is stabilized by two C-H⋯O and two C-H⋯N intra-molecular hydrogen bonds. The crystal packing is dominated by van der Waals inter-actions. Three atoms of the phenyl ring of the benzohydrazidate moiety are disordered over two sets of sites in a 0.625 (18):0.375 (18) ratio.

Bis{?-4-chloro-N'-[(E)-1-(5-chloro-2-oxidophen-yl)ethyl-idene]benzohydrazidato}bis-[pyridine-copper(II)].

Project description:The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.

Poly[bis-{?-N'-[(pyridin-4-yl)methyl-idene]benzohydrazidato}copper(II)].

Project description:In the title complex, [Cu(C13H10N3O)2] n , the copper(II) cation is located on a crystallographic inversion centre and adopts an elongated octa-hedral coordination geometry with the equatorial plane provided by trans-arranged bis-N,O-chelating acyl-hydrazine groups from two ligands and the apices by the N atoms of two pyridine rings belonging to symmetry-related ligands. The ligand adopts a Z conformation about the C=N double bond. The dihedral angle between the pyridine and phenyl rings is 2.99?(13)°. An intra-ligand C-H?N hydrogen bond is observed. In the crystal, each ligand bridges two adjacent metal ions, forming a (4,4) grid layered structure. ?-? stacking inter-actions [centroid-centroid distances in the range 3.569?(4)-3.584?(9)?Å] involving rings of adjacent layers result in the formation of a three-dimensional supra-molecular network.

N-(9H-Fluoren-9-yl-idene)-4-methyl-aniline.

Project description:In the title compound, C(20)H(15)N, the fluorene unit is essentially planar [r.m.s. deviation 0.0334?Å] and the benzene ring bound to the imine N atom bears a methyl group which is nearly coplanar [dihedral angle 0.5?(1)°]. The dihedral angle between the substituent benzene ring and the 9H-fluoren-9-imine unit is 71.1?(3)°. Inter-molecular ?-? inter-actions between the benzene rings of adjacent fluorene units [centroid-centroid distance 3.8081?(13)?Å] are present in the crystal structure, resulting in a one-dimensional supra-molecular architecture.

Project description:The title compound, C(19)H(11)NO, is stabilized by one intra-molecular C-H?O hydrogen bond. The compound can be synthesized in good yield (49%), by transformation of functional groups [starting with 5-(fluoren-9-ylidenemeth-yl)furan-2-carbaldehyde].

Project description:In the title compound, [Co(C(19)H(13)ClN(3)O)(2)]NO(3)·2CH(3)OH, the central Co(III) atom in the cation is surrounded by two tridentate ligands in a distorted octa-hedral fashion by four N and two O atoms. Classical O-H⋯O hydrogen bonds link both methanol solvent mol-ecules with the nitrate anion.

(Z)-tert-Butyl 2-(4-amino-9H-fluoren-9-yl-idene)acetate.

Project description:The title compound, C(19)H(19)NO(2), obtained as an almost equimolar mixture (as shown by (1)H NMR) with the E isomer through a Wittig reaction between 4-amino-9H-fluoren-9-one and the stabilized ylide Ph(3)P=CHCO(2)C(CH(3))(3), was obtained pure in the Z configuration following crystallization from toluene. The mol-ecule shows a planar arrangement of the ring system and the new double bond, whereas the carbonyl O atom forms a 45.1?(3)° dihedral angle with it. The mol-ecules are linked by N-H?O hydrogen bonds, forming cyclic structures with R(4) (4)(24) graph-set motifs. These motifs are connected to each other, giving rise to a sheet structure parallel to the ab plane. The linkage within the sheets is further enhanced by ?-? stacking inter-actions between the fluorene units [centroid-centroid distance = 3.583?(2)?Å].

Project description:In the title compound, [Cu(2)(C(15)H(12)N(2)O(4))(2)(C(6)H(5)N)(2)], each Cu(II) atom is chelated by the tridentate doubly deprotonated Schiff base and a pyridine mol-ecule in a nearly planar environment (r.m.s. deviation for all non-H atoms = 0.107?Å). The metal ions are bridged by one O atom from the symmetry-related Schiff base ligands, forming a centrosymmetric dinuclear copper(II) complex. The dimeric complex is linked to another dimer via weaker Cu-O inter-actions and also O-H?N hydrogen bonds.

N-[(9H-Fluoren-9-yl-idene)(2-meth-oxy-phen-yl)meth-yl]-1,1,1-tri-methyl-silanamine.

Project description:The title mol-ecule, C24H25NOSi, is a hydrolysis product of the reaction between 9-tri-methyl-silyfluorenyl lithium and 2-meth-oxy-benzo-nitrile. The fluorene ring system is substanti-ally planar, with an r.m.s. deviation of 0.0288?Å from the best-fit plane through its 13?C atoms. This plane forms a dihedral angle of 58.07?(7)° with the 2-meth-oxy-benzyl-amine ring plane. In the crystal, mol-ecules are linked by N-H?? and C-H?? inter-actions, which leads to the formation of two-dimensional network lying parallel to the bc plane.
