The title compound, N,N′-bis(2-hydroxy-3,5-dimethylbenzyl)-N,N′-dimethyl-1,2-ethanediamine, was synthesized and the crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. It crystallizes in the monoclinic space group C2/c with a = 17.319(3)Å, b = 9.7041(17)Å, c = 13.352(2)Å, β = 114.032(3)°, V = 2049.4(6)Å3, Dx = 1.155 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0524 and 0.1629, respectively, for all 2432 independent reflections. The molecule is twisted at the ethylendiamine moiety of the ligand with a dihedral angle between the two phenolate planes of 13.58(7)°.
The compound of (Z)-1-[4-(trifluoromethyl)benzylidene]thiosemicarbazide crystallizes in the triclinic space group P1 and Z = 2 with cell parameters a = 7.0109(8)Å, b = 11.7862(13)Å, c = 14.9095(16)Å, α = 111.814(2)°, β = 91.720(2)°, γ = 101.036(2)° and V = 1115.7(2)Å3. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.0438 and wR2 = 0.1078. In the crystal, each molecule is linked by intermolecular N–H···S hydrogen bonds.
A dinuclear nickel(II) complex with N,N′-disalicylidene-2,2′-(ethylenedioxy)bis(ethylamine) (H2dee), [Ni2(dee)2(μ-H2O)]·2EtOH (1), was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. The complex crystallizes in the monoclinic space group C2/c with a = 18.321(8), b = 13.543(6), c = 18.649(9)Å, β = 108.372(8)°, V = 4391(3)Å3, Dcalcd = 1.416 g/cm3, Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0347 and 0.0736, respectively, for all 5014 independent reflections. The complex is composed of a dinuclear molecule with di-μ-phenolato-bridges of dee2− and the μ-aqua-bridge, and crystal ethanol molecules. The electronic spectral feature is consistent with the octahedral geometry of the nickel(II) ions.
A methanesulfonate salt of 3-(N-methyl)quinolinium boronic acid, [3-(N-Me)QnB(OH)2]CH3SO3, was structurally determined by X-ray analysis. The boronic acid salt was crystalized as: P21/c, a = 8.57927(17), b = 6.99494(16), c = 21.0760(4)Å, β = 99.4787(19)°, Z = 4, V = 1247.53(4)Å3. In the single crystal, hydrogen-bonded 1D-array structures of asymmetric cation-anion units were observed.
The crystal structure of the title complex, [Ru(pic)(bpy)2]Cl·CH3CN·1.5H2O (pic = 2-picolinato; bpy = 2,2′-bipyridine), was determined by X-ray crystallography. Single crystals were obtained by the vapor diffusion of diethyl ether into an acetonitrile solution of [Ru(pic)(bpy)2]Cl. The complex crystallized in a monoclinic system, and was characterized as: I2/a, a = 15.40850(14), b = 13.07370(14), c = 27.3830(3)Å, β = 98.0922(9)°, Z = 8, V = 5461.27(10)Å3. The R1 and wR2 values were 0.0267 and 0.0714, respectively, for 5008 reflections.
The crystal structure of the title compound, (C17H28N)[Ni(dmit)2] (dmit = 2-thioxo-1,3-dithiole-4,5-dithiolato, C3S52−) is characterized by its unusually bent molecular structure in which two ligands, C3S52− in [Ni(dmit)2]−, have a gradient of 19.01(6)° to one another, and [Ni(dmit)2]− anions are found to form a one-dimensional network in the direction of the a axis by intermolecular S–S contacts between the adjoining anions located almost vertically. Among these vertically arranged anions, the dihedral angle between the adjacent planes of the anions (S–S–Ni–S–S) is 69.51(2)°.
