The characterized organic trihydrate title salt, C17H17N4 +·C7H5O5 -·3H2O or (HL)+(Gal)-·3H2O, with L = 1,3-bis-(1H-benzimidazol-2-yl)propane (C17H16N4) and HGal 3,4,5-tri-hydroxy-benzoic acid (gallic acid, C7H6O5), crystallizes two formulas per asymmetric unit. One-half of the cations in crystal feature a bent shape, central propyl chain having gauche conformation, other half is nearly linear, trans chain. Both form independent herringbone layers crystal, which allow efficient π-π...
Reaction of [MS4]2–(M = Mo or W) with CuCl in dichloromethane acetonitrile gives a new set bimetallic compounds isolated various geometries for the same 1:4:4 M:S:Cu composition. Crystals [NBu4]2[MoS4Cu4Cl4]1a are tetragonal, space group I/m, a= 13.343(5), c= 14.113(2)Å, Z= 2, R= 0.058. The crystal structure reveals discrete [MoS4Cu4Cl4]2– anions separated lattice by [NBu4]+ cations. isostructural tungsten homologue 1b was and characterized: 13.342(4), 14.106(5)Å. [PPh4][NPr4][MoS4Cu4Cl4]2...
A chelating coumarin-derived ligand sensitizes all emitting lanthanide ions in the solid state and gives high absolute quantum yields for ethanol solutions of complexes Sm, Eu, Tb, Dy, above 20% last two. Crystal structures these four are [Ln(Cum)3(H2O)(X)]·X where X = MeOH or EtOH.
The reaction of [Pt(PEt3)3], 1, with 3-methylbenzothiophene and 2-methylbenzothiophene afforded the thiaplatinacycles [(Et3P)2Pt(C,S-C9H8S)], 3 4, respectively. In formation both complexes (Et3P)2Pt has inserted into C−S bond to vinylic carbon. Complex 4 rearranges in solution a dimeric thiaplatinacycle, 5, which platinum moved from lying between aromatic bond. Reaction 1 4-methyldibenzothiophene gave mixture isomeric [(Et3P)2Pt(C,S-C13H10S)], 6 7. 4,6-dimethyldibenzothiophene containing...
The trinuclear copper(II) complex [Cu3(cpse)3(H2O)3]·8.5H2O has been obtained from mononuclear [Cu(Hcpse)2]·H2O {H2cpse = N-[2-hydroxy-1(S)-methyl-2(S)-phenylethyl]-N-methylglycine, threo isomer} and crystallographically characterised. structure of the compound consists three CuII atoms, each having distorted square-pyramidal geometry, linked by oxo-bridges to form an equilateral triangular array. magnetic behaviour corresponds antiferromagnetically coupled system, with J −114.2 cm−1. EPR...
Abstract Three new compounds were formed between decavanadate and diprotonated metformin (H 2 Metf) at different pH values in the presence or absence of ammonium cations, namely, [H Metf] 3 [V 10 O 28 ] · 8H ( 1 ), [NH 4 10H 4H ). We present their spectroscopic, thermal, single‐crystal X‐ray diffraction characterization. The solid‐state structure shows that three H Metf 2+ dications counterbalance charge anion are close vicinity latter, as a result strong Coulombic forces arise from ionic...

The reaction of dibenzothiophene (DBT) with [Ru3(CO)12] in heptane affords the dinuclear complex [Ru2(C12H8)(μ-CO)(CO)5], derived from a double C−S bond activation−desulfurization process. this H2 under very mild conditions leads to release biphenyl.
Abstract The structural, electronic, magnetic and theoretical study of the complex [Co 3 (HL) 2 ( μ ‐AcO) (AcO) ], 1 , (HL is dianion obtained by deprotonation N,N’‐bis(salicylidene)‐2‐hydroxy‐1,3‐propanediamine AcO acetate) shows that crystallizes with two independent molecules in asymmetric unit. Each molecule a trinuclear complex. Both have similar geometry, correspond to spin system based on trapped mixed valences six‐coordinate metal centres, Co III s =0)‐Co II =3/2)‐Co =0). rigid...
