A monoclinic polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine.

ABSTRACT: A new polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine, C(25)H(36)N(2), is reported, which is different from the previously reported ortho-rhom-bic structure. The mol-ecule crystallizes in the E-anti configuration, with tautomeric disorder of the N-bonded H atoms and no clear distinction between imine and amine functionalities. The mol-ecules form hydrogen-bonded dimers with inter-molecular N?N distances shorter than those in the ortho-rhom-bic polymorph.

A new polymorph of N,N'-bis-(2,6-diisopropyl-phen-yl)formamidine, C(25)H(36)N(2), is reported, which is different from the previously reported ortho-rhom-bic structure. The mol-ecule crystallizes in the E-anti configuration, with tautomeric disorder of the N-bonded H atoms and no clear distinction between imine and amine functionalities. The mol-ecules form hydrogen-bonded dimers with inter-molecular N⋯N distances shorter than those in the ortho-rhom-bic polymorph. ...[more]

N,N'-Bis[3,5-bis-(2,6-diisopropyl-phen-yl)phen-yl]butane-2,3-diimine.

Project description:The title mol-ecule, C(64)H(80)N(2), lies on an inversion center wherein the central butane-diimine fragment [N=C(Me)-C(Me)=N] is essentially planar [maximum deviation = 0.002?(2)?Å] and its mean plane forms a dihedral of 70.88?(10)° with the attached benzene ring. In the symmetry-unique part of the mol-ecule, the dihedral angles between the benzene ring bonded to the N atom and the other two benzene rings are 89.61?(6) and 82.77?(6)°.

Bis(2,6-diisopropyl-phen-yl) sulfite.

Project description:In the title compound, C(24)H(34)O(3)S, the dihedral angle between the benzene rings is 84.62?(8)°. In the crystal, inter-molecular C-H?O hydrogen bonds link mol-ecules into zigzag chains running parallel to the c axis. The C atoms of two isopropyl groups are disordered over two sets of sites with occupancy ratios of 0.858?(9):0.142?(9) and 0.61?(5):0.39?(5).

N-(2,6-Diisopropyl-phen-yl)formamide.

Project description:The title compound, C(13)H(19)NO, exhibits a non-planar structure in which the 2,6-diisopropyl-phenyl ring is tilted at a dihedral angle of 77.4?(1)° with respect to the formamide group. This is the largest dihedral angle known among structurally characterized formamides. The mol-ecules are linked via N-H?O hydrogen bonds, forming infinite chains which run along the b-axis directions.

N-(2,6-Diisopropyl-phen-yl)-N-{3-[(2,6-diisopropyl-phen-yl)imino]-butan-2-yl}aza-nide trichloridostannate(II).

Project description:In the title compound, (C(28)H(43)N(2))[SnCl(3)], two pairs of molecular species are present in the asymmetric unit. The employed ?-diimine opens up, forming a highly asymmetric ammonium that has its protons at one of the N atoms [N-C= 1.264?(4) and 1.516?(4)?Å]. One of the C=N double bonds was oxidized to C-N, which is consistent with the bond length of 1.516?(4)?Å. Meanwhile Sn(IV) was reduced to Sn(II). The (SnCl)(3) (-) anion is trigonal-pyramidal. In the crystal, mol-ecules are linked by C-H?Cl, N-H?Cl, N-H?N and C-H?N bonds. The crystal studied was twinned by pseudo-merohedry.

N-(2,6-Diisopropyl-phen-yl)thio-amide.

Project description:In the crystal structure of the title compound, C(13)H(19)NS {systematic name: N-[2,6-bis-(propan-2-yl)phen-yl]carbothio-amide}, mol-ecules assemble via N-H?S=C hydrogen bonds into helical chains along the b axis. The thio-amide moiety, with a syn disposition of the N- and C-bound H atoms, is twisted out of the plane of the benzene ring to which it is connected, forming a dihedral angle angle of 77.60?(14)°.

Di-?-chlorido-bis-({9-[(2,6-diisopropyl-phen-yl)imino-meth-yl]anthracen-1-yl}palladium(II)).

Project description:The centrosymmetric title compound, [Pd(2)Cl(2)(C(27)H(26)N)(2)], was obtained by a C-H bond-activation reaction of a Schiff base ligand with Li(2)PdCl(4) in methanol, and was crystallized from dichloro-methane as orange crystals. The Pd atom displays a slightly distorted square-planar geometry, with the N- and C-atom donors in a cis arrangement.

1,4-Bis(4-bromo-2,6-diisopropyl-phen-yl)-1,4-diaza-buta-1,3-diene.

Project description:The molecule of the title compound, C(26)H(34)Br(2)N(2), lies on a crystallographic inversion center and hence the two imine groups are s-trans. The dihedral angle between the central 1,4-diaza-buta-1,3-diene unit and the attached substituted phenyl ring is 88.4?(7)°. The structure features a C-H?N close contact. The crystal selected for this study proved to be a non-merohedral twin with a minor component of 21.8?(3)%.

1,3-Bis(2,6-diisopropyl-phen-yl)imidazolidinium tetra-phenyl-borate dichloro-methane disolvate.

Project description:The title compound, C(27)H(39)N(2) (+)·C(24)H(20)B(-)·2CH(2)Cl(2), is the first reported imidazolidinium cation with the sterically demanding 2,6-diisopropyl-phenyl groups in the 1,3-positions. The crystal structure is stabilized by weak inter-molecular C-H??(arene) inter-actions. Due to the bulky nature of both the flanking 2,6-diisopropyl-phenyl substituents and the tetra-phenyl-borate counter-ion, anion inter-actions with the imidazolidinium H atom in the 2-position are not observed, also a first for this class of ortho-alkyl-substituted Arduengo-type carbene precursors.

Project description:In the crystal structure of the title compound, C(27)H(39)N(2) (+)·I(3) (-), the imidazolidinium ring is perpendicular to a mirror plane which bis-ects the cation.
