Cis-Bromido(methyl-amine)-bis-(propane-1,3-di-amine)-cobalt(III) dibromide.

ABSTRACT: In the title compound, [CoBr(CH5N)(C3H10N2)2]Br2, the cobalt(III) ion has a distorted octa-hedral coordination environment and is surrounded by four N atoms in the equatorial plane, with an additional N atom and the Br atom occupying the axial positions. In the crystal, the complex cation and the two counter anions are linked via N-H?Br and C-H?Br hydrogen bonds, forming a three-dimensional network.

catena-Poly[[[diaqua-cobalt(II)]bis-(μ-1,3-di-4-pyridylpropane-κN:N')] bis-(perchlorate) bis-(1,3-di-4-pyridyl-propane) bis-(2-methyl-4-nitro-aniline)].

Project description:In the title compound, {[Co(C(13)H(14)N(2))(2)(H(2)O)(2)](ClO(4))(2)·2C(13)H(14)N(2)·2C(7)H(8)N(2)O(2)}(n), the Co(II) ion lies on a crystallographic inversion center and is coordinated by four N atoms from four symmetry-related 1,3-di-4-pyridylpropane ligands and two O atoms from two water ligands in a slightly distorted octa-hedral coordination environment. The 1,3-di-4-pyridylpropane ligands are doubly bridging and connect the Co(II) ions into one-dimensional chains. The asymmetric unit also contains one uncoordinated 1,3-di-4-pyridylpropane mol-ecule, one 2-methyl-4-nitro-aniline mol-ecule and one perchlorate anion. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds connect the one-dimensional chains into a two-dimensional network.

Crystal structure of di-bromido-bis-(1,3-dibenzyl-1,3-diazinan-2-one-κO)cobalt(II).

Project description:The unit cell of the title complex, [CoBr2(C18H20N2O)2], contains 1.5 formula units per asymmetric unit with one mol-ecule sitting on a general site and a second one halved by a crystallographic twofold rotation axis passing through the Co(II) cation. Both Co(II) atoms are coordinated in a distorted tetra-hedral manner by two Br(-) ligands and two O atoms of the pyrimidinone (OPyr) groups. The Br-Co-Br coordination angles are similar [115.46 (4) and 115.20 (5)°], while the O-Co-O angles differ slightly more [102.26 (18) and 98.1 (2)°]. Similarly, the Co-Br bond lengths are almost identical [2.3721 (9), 2.3757 (10) and 2.3809 (10) Å], with a larger difference between the Co-O bond lengths [1.929 (4), 1.926 (4) and 1.955 (4) Å]. The three independent OPyr groups present envelope conformations, with three C and two N atoms lying in well defined planes with maximum deviations from the least-squares planes of 0.047, 0.031 and 0.036 Å, and the external-most C atoms protruding by 0.654 (6), 0.643 (7) and 0.656 (6) Å out of the planes. The dihedral angles between the planar fractions of the OPyr planes are 50.5 (1)° for the nonsymmetric mol-ecule and 49.7 (1)° for the symmetric one. Non-covalent inter-actions are of the C-H⋯Br type and they are weak, hardly shorter than van der Waals radii, with an H⋯Br distance range of 3.00-3.04 Å. The inter-molecular inter-actions define chains parallel to [101].

Bis[tris(propane-1,3-diamine-?(2) N,N')-nickel(II)] di-aqua-bis(propane-1,3-di-amine-?(2) N,N')nickel(II) hexa-bromide dihydrate.

Project description:In the title compound, [Ni(C3H10N2)3]2[Ni(C3H10N2)2(H2O)2]Br6·2H2O, one Ni(2+) cation, located on an inversion centre, is coordinated by four N atoms from two ligands and by two water O atoms. The other Ni(2+) cation, located in a general position, is coordinated by six N atoms from three ligands. In both cases, the Ni(2+) cation has an octa-hedral coordination environment. The overall structural cohesion is ensured by three types of hydrogen bonds, N-H?Br, O-H?Br and O-H?O, which connect the two types of complex cations, the bromide counter-anions and the lattice water molecules into a three-dimensional network.

Project description:The title compound, C(25)H(30)N(4) (2+)·2Br(-)·H(2)O, was synthesized from 1,1'-propyl-enedibenzimidazole and (E)-1-bromo-but-2-ene in dimethyl-formamide solution. The two benzimidazole ring systems are essentially planar, with maximum deviations of 0.011 (4) and 0.023 (3) Å. The dihedral angle between these two ring systems is 25.87 (15)°. The crystal structure is stabilized by inter-molecular O-H⋯Br and C-H⋯Br hydrogen-bonding inter-actions. Atmospheric water was incorporated into the crystal structure.

{[2-Methyl-2-(phen-oxy-meth-yl)propane-1,3-di-yl]bis-(-oxy)}di-benzene.

Project description:The title compound, C23H24O3, was obtained in a one-step (60% yield) synthesis from 1,1,1-tris(hydroxymethyl)ethane. It features a tripodal ligand capable of complexing metal centres. One of the three conformations involving the methyl group, the central C-C bond and the phenoxy substituents is antiperiplanar while the two others are synclinal [the corresponding C-C-C-O torsion angles are -174.6?(1), -53.2?(2) and -47.3?(2)°]. In the crystal, C-H?O inter-actions link the molecules into [010] chains.

Project description:The title compound, C(21)H(22)Br(2)N(4)·0.5H(2)O, contains two benzimidazole groups which may provide two potential coordination nodes for the construction of metal-organic frameworks. The mean planes of the two imidazole groups are almost perpendicular, with a dihedral angle of 83.05 (2)°, and adjacent mol-ecules are linked into a one-dimensional chain by π-π stacking inter-actions between imidazole groups of different mol-ecules [centroid-to-centroid distances of 3.834 (2) and 3.522 (2) Å].

Bis(?-2-hy-droxy-methyl-2-methyl-propane-1,3-diolato)bis-[di-chlorido-titanium(IV)] diethyl ether disolvate.

Project description:The title complex, [Ti2Cl4{CH3C(CH2O)2(CH2OH)}2], lies across a centre of symmetry with a diethyl ether solvent mol-ecule hydrogen bonded to the -CH2OH groups on either side of it. The Ti(IV) atom is coordinated in a distorted octa-hedral geometry by a tripodal ligand and two terminal chloride atoms. There are three coordination modes for the tripodal ligand distinguishable on the basis of their very different Ti-O bond lengths. For the terminal alkoxo ligand, the Ti-O distance is 1.760?(1)?Å, the asymmetric bridge system has Ti-O bond lengths of 1.911?(1) and 2.048?(1)?Å. The Ti-O bond length for the alcohol O atom is the longest at 2.148?(1)?Å.
