Bis[2,3,4-trimethyl-5-[(3,4,5-trimethyl-2H-pyrrol-2-yl-idene-?N)meth-yl]-1H-pyrrolato-?N]copper(II).

ABSTRACT: In the title complex, [Cu(C(15)H(19)N(2))(2)] or [Cu(L(2))] (HL is 3,3',4,4',5,5'-hexa-methyl-pyrromethene), the Cu(II) atom is coordinated by four N atoms [Cu-N 1.939?(2)-1.976?(2)?Å] from two L ligands in a distorted tetra-hedral geometry. The mean planes of the CuN(2)C(3) metallocyclic rings form a dihedral angle of 72.73?(6)°. In the L ligands, the pyrrole rings are inclined to each other at dihedral angles of 3.03?(7) and 9.83?(7)°. The crystal packing exhibits weak inter-molecular C-H?? inter-actions, which form chains in [100].

Project description:In an effort to discover novel and potential boron-dipyrromethene (BODIPY) dyes, the title compound, C(19)H(18)BF(2)N(3)O(2), was prepared from 2,4-dimethyl-pyrrole, 4-nitro-benzaldehyde and BF(3)·Et(2)O in a one-pot reaction. There are two independent mol-ecules, A and B, in the asymmetric unit in which the dihedral angles between the benzene ring and boron-dipyrromethene mean plane have significantly different values [82.71?(8)° for mol-ecule A and 73.16?(8)° for mol-ecule B]. Inter-molecular C-H?? inter-actions help to stabilize the crystal structure.

(E)-2,4,6-Trimethyl-N-[(1H-pyrrol-2-yl)methyl-idene]aniline.

Project description:The title compound, C14H16N2, is a pyrrole-2-carbaldimine ligand that shows an E conformation at the imine double bond. The dihedral angle between the rings is 78.3?(1)°. In the crystal, pairs of mol-ecules form centrosymmetric dimers [graph-set descriptor is presumably R(2)2(10)] via N-H?N hydrogen bonds between the pyrrole N-H group and the imine N atom of a neighbouring mol-ecule.

2,4,6-Trimethyl-N-[1-(1H-pyrrol-2-yl)ethyl-idene]aniline.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(18)N(2), each of which features a syn disposition of the N atoms. In each mol-ecule, the pyrrole and benzene rings are essentially perpendicular, with dihedral angles of 78.90?(9) and 79.96?(9)°. In the crystal, the independent mol-ecules are connected by a pair of pyrrole-imino N-H?N hydrogen bonds, forming a two-mol-ecule aggregate.

Project description:In the title compound, C15H23N3O3, the piperazine ring is in a slightly distorted chair conformation and is twisted from the mean plane of the benzene ring making a dihedral angle of 14.94 (6)°. The 4-meth-oxy substituent is almost co-planar with the benzene ring [C-C-O-C torsion angle = 5.4 (1)°], while the meth-oxy groups at positions 2 and 3 [C-C-O-C torsion angles of 122.6 (4) and -66.1 (4)°, respectively] are twisted away from the mean plane of the benzene ring in anti-clinical and synclinical conformations, respectively. No classical hydrogen bonds or any weak inter-molecular inter-actions are observed in the crystal structure.

Project description:The title compound, C25H31BF2N2O, is a potential boron tracedrug in boron neutron capture therapy (BNCT), in which the B atom adopts a distorted BN2F2 tetra-hedral geometry: it is soluble in dimethyl sulfoxide, di-methyl-formamide and methanol. The pyrrolyl-idene-methyl-pyrrole triple fused ring system is almost planar (r.m.s. deviation = 0.031 Å) and subtends a dihedral angle of 47.09 (5)° with the plane of the pendant phenol ring. The phenol -OH group is blocked from forming hydrogen bonds by the adjacent bulky tert-butyl groups. In the crystal, inversion dimers linked by pairs of very weak C-H⋯F inter-actions generate R 2 (2)(22) loops.
