“…Thus in summary the above experiments lead us to conclude with some confidence that cis-[Pd(bit) 2 (j 2 -dppm)] (19) and [Pd(bit) 2 (j 1 -dppm) 2 ] (20) are the major products from reactions of [PdCl 2 (j 2 -dppm)] and [Pd(j 2 -dppm) 2 ]Cl 2 respectively with two equivalents of Na [bit]. Reaction of 1 with dppm appears to be less selective and leads together with 19 and 20 to the generation of a third species somewhat more tentatively assigned as [Pd 2 (bit) 4 (l-dppm) 2 ] (21) which is also formed in small amounts in the other two reactions.…”

“…The major species in solution (ca. 55%) exhibited a singlet resonance at À46.5 ppm and we tentatively assign this to the target product cis-[Pd(bit) 2 (j 2 -dppm)] (19) as it is well-documented that constraining dppm into a fourmembered ring results in a significant up-field shift of the 31 P chemical shift [24,25]. The next major species (ca.…”

“…Similar behavior viz. their relatively poor solubility in common organic solvents and inclusion of one water per metal atom, is seen in related tsac complexes [M(tsac) 2 ]ÁH 2 O (M = Pd, Pt) [19]. On the basis of the data that we have we cannot discern between monomeric (A) and dimeric (B) structural motifs (Chart 2) or indeed a polymeric structure (not shown) but we discount the latter on the basis of their solubility in organic solvents.…”

“…Thus trans-[PdCl 2 (apy) 2 ] [19] was reacted with two equivalents of Na [bit] in EtOH to give a yellow precipitate characterized as trans-[Pt(apy) 2 (bit) 2 ] (9) (Scheme 4). The complex is soluble in CDCl 3 and a 1 H NMR spectrum confirmed the 1:1 ratio of amine and benzisothiazolinate ligands.…”

a b s t r a c tA series of square-planar palladium(II) benzisothiazolinate (bit) of the general type [Pd(bit) 2 L 2 ] have been prepared and characterized by analytical and spectroscopic methods. Two synthetic routes have been employed, namely reactions of [Pd(bit) 2 ]ÁH 2 O with two equivalents of ligands (L = amine, amide, phosphine) or nucleophile displacement of chloride by benzisothiazolinate starting from trans-[PdCl 2 L 2 ]. Both routes afford the new complexes in good yields as easily isolated, air and moisture stable, colored solids. The precursor, [Pd(bit) 2 ]ÁH 2 O, is itself prepared in high yields upon reaction of Na[bit] with Na 2 [PdCl 4 ] in methanol and the analogous platinum complex, [Pt(bit) 2 ]ÁH 2 O, is similarly prepared from K 2 [PtCl 4 ]. It is not clear if these species are mono-or dimeric, and formulation as [M 2 (l-bit) 4 (H 2 O) 2 ] with the four benzisothiazolinate spanning the metal-metal vector and possibly binding through coordination of nitrogen and oxygen is suggested. Diphosphine adducts, cis-[Pd(bit) 2 {j 2 -Ph 2 P(CH 2 ) n PPh 2 }] (n = 1-4) can be prepared both upon addition of the diphosphine to [Pd(bit) 2 ]ÁH 2 O and from reactions of cis-[PdCl 2 {j 2 -Ph 2 P(CH 2 ) n PPh 2 }] with two equivalents of Na [bit]. A crystal structure of cis-[Pd(bit) 2 (j 2 -dppe)] reveals that the benzisothiazolinate ligands are bonded in a monodentate fashion through nitrogen and this binding mode is proposed for all [Pd(bit) 2 L 2 ] and [Pd(bit) 2 L] complexes. With dppb (n = 4) a second product is seen by NMR spectroscopy being proposed to be the part-substituted complex cis-[PdCl(bit)(j 2 -dppb)], while with dppm (n = 1) two further products are seen spectroscopically, proposed as trans-[Pd(bit) 2 (j 1 -dppm) 2 ] and (more tenuously) [Pd 2 (bit) 4 (dppm) 2 ]. The former is also prepared in good yields from reaction of [Pd(j 2 -dppm) 2 ]Cl 2 with Na [bit]. These studies show that palladium benzisothiazolinate are easily accessed and show good air and moisture stability.

ABSTRACT-dppmCl)Cl 2 ] complexes and then add the ligand HSBIBT to these complexes to form mixed ligand complexes. The prepared complexes have been characterized by single-crystal X-ray diffraction, elemental analysis, magnetic susceptibility, molar conductance, IR spectral data and UV-Visible. The results suggested that the ligand HSBIBT bonded to the metal through N atom and square planner geometries were assigned for the complexes.

A tetrahedral Hg(II) diethyl dithiocarbamate (Et 2 Dt) complex containing triphenylphosphine (PPh 3 ) of the composition [HgCl(κ 2 -Et 2 Dt) 2 (PPh 3 )] (1) is prepared. Furthermore, complex (1) is used as a synthone to prepare a novel series of complexes of the following composition [Hg(Et 2 Dt)L(PPh 3 )] {L = saccharinate (2), thiosaccharinate (3), benzisothiazolinate (4), benzothiozole-2-thiolate (5), and benzooxazole-2-thiolate (6) anions}. The resulted complexes(1)-(6) are characterized by elemental analysis, molar conductivity, powder X-ray diffraction, fourier transform Infrared, and NMR ( 1 H and 31 P) spectroscopic techniques. The Et 2 Dt ligand is coordinated as bidentate chelate through the sulfur atoms, whereas the L ligands are bonded as monodentate ligands to afford a tetrahedral geometry around the Hg(II) ion. Nitrogen adsorptiondesorption isotherm for two of as-prepared complexes (2) and (3) are measured first to get their Brunauer-Emmett-Teller surface area. Moreover, the mentioned two complexes are evaluated for their ability to store hydrogen gas at 77 K. However, the results of the hydrogen storage tests proved that the selected complexes are all capable of storing hydrogen, but in varying degrees, where complex (2) exhibited a storage capacity of 4.22 wt% under 88 bar.
