The structural chemistry of metal complexes with bis(thiophosphoryl) and bis(thiophosphinyl) disulfides has been extensively reviewed.1 The reactive –S–S– functional moiety determines the chemical properties of these thermally stable disulfides, and their photolytic properties are important in photochemically activated reactions. Bis(thiophosphoryl)disulfides act as potentially significant stabilizers for polymer composition, as vulcanization accelerators, and as antioxidants. These disulfides also act as antiwear additives in ash-less and extreme pressure engine lubricants, and are involved in the mechanism of the antioxidant action of metal dithiophosphate lubricant oil additives. Some bis(thiophosphoryl)disulfides show fungicidal activity. Due to the significance of the disulfide bond in natural products, the physiochemical properties of –S–S– linkages have been extensively studied over the last few decades. Molecular structures of several organothiophosphoryl disulfides have been determined, including [{(i-Pr)O}2PS2]2, [(PhO)2PS2]2, and [OCMe2CMe2OPS2]2 which provide for comparisons with the structure of bis[O,O¢-di(p-tolyl)thiophosphoryl]disulfide, [(p-MeC6H4O)2PS2]2. The title compound was prepared by a literature method.5 An orange block crystal of [(p-MeC6H4O)2PS2]2 was mounted in a capillary within a glove box, thus maintaining a dry, O2-free environment for each crystal. No statistically significant change over the duration of the data collection was observed. Experimental details and results are given in Table 1. All of the non-hydrogen atoms were treated anisotropically. Hydrogen atoms were included at idealized positions with isotropic thermal parameters. The distances and bond angles are given in Table 2.

The cobalt(III) azido complex, Na[Co(salen)(N3)2], contains a Co(III) cation in a distorted octahedral coordination. The equatorial plane of the octahedron is defined by two N and two O atoms from the tetradentate salen ligand, and the axial ligands belong to two terminal N atoms from two different azide anions. Via interactions between the Na+ cations and the N and O atoms of the ligands, the [Co(salen)(N3)2]- anions are connected into a polymeric structure, forming corrugated ribbons parallel to [100].

The use of palladium complexes to catalyze the coupling of organoboron compounds with aryl or vinyl halides has become one of the most widely used tools in organic synthesis. The scope and utility of the Suzuki–Miyaura reaction has been the subject of several excellent reviews.1 The use of boronic acids in this cross coupling process is especially advantageous as these compounds are relatively nontoxic and thermally, airand moisture-stable.2 Numerous advances have been made to this reaction since its discovery. For instance, the use of aryl chlorides as substrates and the ability to conduct the reaction at low temperature and at low catalyst loading have greatly increased the versatility of the Suzuki–Miyaura cross coupling reaction. Catalyst development has also played a significant role in improving this reaction as traditional palladium complexes used to catalyze this transformation contain airsensitive phosphine ligands. In recent years, a considerable amount of research has also focused on designing new catalysts that can be used to carry out this reaction in alternative solvents.3 We report here on the synthesis and molecular structure of a palladium complex containing fluorinated benzylamines for its potential use in the Suzuki–Miyaura cross-coupling reaction. A suspension of PdCl2 (150 mg, 0.85 mmol) in MeOH (15 mL) was treated with NaCl (100 mg, 1.71 mmol) at RT and stirred for 1 h. A MeOH (2 mL) solution of 4fluorobenzylamine (212 mg, 1.69 mmol) was added dropwise to the reaction mixture and stirred for 1 h resulting in the formation of a yellow precipitate. The solid was collected by suction filtration and washed with MeOH (5 mL) and hexane (10 mL) to afford the title compound. Crystals were obtained by recrystallization from DMSO at RT. Yield: 290 mg (80%); m.p. = 495 – 497 K (decomposition).

The salt 1-2 diphenyl ethylenediammonium chloride crystallizes at room temperature in the monoclinic system with polar space group P21; the unit-cell dimensions are: a = 8.720(2), b = 6.243(2), c = 13.972(5)A, β = 106.67(3)° with Z = 2. The structure consists of [C14H18N2]2+ cations and isolated chlorine anions. These entities are linked together through N-H…Cl hydrogen bonds, forming a three-dimentional network.
