“…The L ligand unit is coordinated to Hg via its Se atom, and two [LHgCl 2 ] units dimerize to form 5, having an inversion center. The Hg-Se distance of 2.4931 (19) Å is shorter and the P-Se distance of 2.229(3) Å is longer than those observed in 2, 4, and 6. In the literature, only three compounds, [HgCl( μ-Cl)(C 4 H 8 Se)] 2 , 25a [HgCl(μ-Cl) (MeSeCH 2 SiMe 3 )] 2 , 25b and [HgCl(μ-Cl)(SePPh 3 )] 2 , 26 have a Hg 2 Cl 2 parallelogram core and display a binding mode of HgSeCl 3 .…”

Reactions of perchlorate salts of Hg(II)/Cd(II) with [CpFe(CO)(2)P(Se)(O(i)Pr)(2)] (denoted as L) produced dicationic clusters [HgL(2)](ClO(4))(2), 1; [HgL(3)](ClO(4))(2), 2; and [CdL(3)(H(2)O)](ClO(4))(2), 11. However, the reactions of L with Hg(II)/Cd(II) halides yielded neutral complexes. For instance, HgI(2) produced [Hg(3)I(6)L(2)], 3, or [HgI(2)L(2)], 4, depending on the metal-to-ligand ratio used. Reaction of L with any of the Hg(II)/Cd(II) halides in a 1:1 ratio produced neutral clusters [HgX(mu-X)L](2) (M = Hg; X = Cl, 5; Br, 6; I, 7; M = Cd; X = Cl, 8; Br, 9; I, 10). Thus, variation of the M-to-L ratio made it possible for the formation of compounds with different metal/ligand stoichiometries only when ClO(4)(-) and I(-) salts of Hg(II) were used. Single-crystal X-ray crystallography revealed that two and three L units were connected to a Hg(II) via its Se atom in 1 and 2, respectively, whereas Hg(II) in 4 was connected to two "I" and two "L" units. An L (through its Se) and a terminal halogen were attached to each of the Hg(II)'s of the Hg(2)X(2) parallelogram core in 5 and 6. The cadmium complex 8, with a Cd(2)Cl(2) parallelogram core, was isostructural with the mercury complex 5. Although bonding and connectivity in 8 were similar to those in 9 and 10, the conformation of the bulky L ligands was unusually syn in 9 and 10, unlike the anti orientation in 5, 6, and 8. The syn conformation of L was also observed in compounds 1 and 2. Secondary interactions, namely, Se...Se interaction, the X...H-C type of H-bonding (X = halogen or Se), and pi-stacking, revealed in the structures played a role in determining the ligand conformation. The [P(Se)(O(i)Pr)(2)](-), the conjugate base of secondary phosphine selenide [HP(Se)(O(i)Pr)(2)], acted as a bridge with P bonded to Fe and Se bonded to Hg (or Cd) in these heterometallic clusters. Compound 5 further demonstrated a longer P-Se bond in the secondary phosphine selenide compared to that in isostructural, tertiary phosphine selenide metal complexes.

“…Previously, various groups of alcohols had been used for FcLR, including methanol, ethanol, and isopropanol and ring opening by ammonia hydrate have been reported . A number of ligands through a combination of S/N/O heterocyclic atoms have been used in the nucleophilic ring opening reaction of the FcLR reagent . The metal complexation chemistry of FcLR is generally scarce, with only a few complexes known, whilst reported metal complexes with the new hydroxy ferrocenyl dithiophosphonate ligand L1 is heretofore unknown.…”

The formation, characterization, and dye sensitized solar cell application of nickel(II), zinc(II) and cadmium(II) ferrocenyl dithiophosphonate complexes were investigated. The multidentate monoanionic ligand [S 2 PFc(OH)] À (L1) was synthesized. The reaction between metal salt precursors and L1 produced Ni(II) complexes of the type [Ni{S 2 P(Fc)(OH)} 2 ] (1) (molar ratio 1:2), and a tetranickel(II) complex of the type [Ni 2 {S 2 OP(Fc)} 2 ] 2 (2) (molar ratio (1:1). It also produced a Zn(II) complex [Zn{S 2 P (Fc)(OH)} 2 ] 2 (3), and a Cd(II) complex [Cd{S 2 P(Fc)(OH)} 2 ] 2 (4). Complexes 1-4 were characterized by 1 H and 31 P NMR, FTIR and elemental analysis, and complexes 1 and 2 were additionally analyzed by X-ray crystallography. The first examples of dyesensitized solar cells (DSSCs) co-sensitized with ferrocenyl dithiophosphonate complexes 1-4 are reported. Co-sensitization with the ruthenium dye N719, produced the dye materials (3)-N719 (η = 8.30%) and (4)-N719 (η = 7.78%), and they were found to have a better overall conversion efficiency than the pure Ru N719 dye standard (η = 7.14%) under the same experimental conditions. The DSSCs were characterized using UV/vis, cyclic voltammetry, electrochemical impedance spectroscopy (EIS), photovoltaic-(IÀ V curves), and performing incident photon-to-current efficiency (IPCE) measurements.
