mono and bis hexamethylenetetramine iron(iii) chloride, fe(n c ,h ) ci (i) and fe(n c ,h ) cl (ii) were synthesized by the reaction of iron(iii) chloride and hexamethylenetetramine (hmta) in chloroform. chemical analysis and spectral results show the coordination of hmta to the iron(iii). electronic transition spectra of compound i and i1 were also studied in coordinating and noncoordinating so...

The title organic-inorganic salt, (C(7)H(11)N(2))(2)[LaCl(H(2)O)(8)]Cl(4)·3H(2)O, consists of two 4-(dimethyl-amino)-pyridinium and one [La(H(2)O)(8)Cl](2+) cations, four chloride anions and three solvent water mol-ecules. In the crystal, the various units are connected by N-H⋯Cl, O-H⋯Cl, O-H⋯O and N-H⋯O hydrogen bonds, forming a network of alternating organic and inorganic layers. The 4-(dimet...

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the...

The crystal structure of the title compound, [Ir(C(10)H(15))Cl(C(21)H(21)PS)]Cl·H(2)O, consists of discrete [Ir(η(5)-C(5)Me(5))Cl{Ph(2)P(CH(2))(3)SPh-κP,κS}](+) cations, chloride anions and water mol-ecules. The Ir(III) atom is coordinated by an η(5)-C(5)Me(5) ligand, a chloride and a Ph(2)P(CH(2))(3)SPh-κP,κS ligand, leading to a three-legged piano-stool geometry. In the crystal, two water mol...

In the title compound, (C(5)H(6)N)(3)[MoCl(4)O(2)]Cl, the pyridinium cations are N-H⋯Cl hydrogen bonded to the anionic [MoCl(4)O(2)](2-) complexes and to the two crystallographically independent chloride anions (located on C2 axes). The Mo(6+) centre adopts a highly distorted octa-hedral geometry, being surrounded by four chloride and two terminal oxide groups. The oxide ligands are mutually cis.

The title compound, [PtCl(C(42)H(78)OP(4))]Cl·0.5CH(2)Cl(2)·4H(2)O, crystallizes as a contact ion-pair with two close inter-molecular C-H⋯Cl(-) contacts between CH acidic αH atoms of the phosphane ligand and the chloride anion. A chloride ligand together with three coordinating P ligand atoms create a slightly distorted square-planar coordination environment around the Pt(II) center. An inter-m...

New diphosphines based on benzofurobenzofuran and dibenzodioxocin backbones, forming exclusively bimetallic complexes were designed and synthesized. Depending on the ligand to metal ratio, face-to-face bimetallic complexes or syn-chloride bridged dimeric complexes were formed as main reaction products. The structures of the rhodium complexes of the new ligands 4, 7, 10, 13, 16 were established ...

In this paper we report on the corrosion inhibition of cast iron in Arabian Gulf seawater by two different ionic liquids namely, 1-ethyl-3-methylimidazolium chloride ([EMIm]Cl) and 1-butyl-1-methylpyrrolidinium chloride ([Py1,4]Cl). The inhibiting influence of the employed ionic liquids was investigated by weight loss, open circuit potential electrochemical impedance spectroscopy, and cyclic po...

Single crystals of the title organic-inorganic hybrid, {(C(5)H(7)N(2))(2)[MnCl(2)(H(2)O)(2)]Cl(2)}(n), were synthesized from an ethanol solution containing manganese(II) chloride tetra-hydrate and 4-amino-pyridine under acidic conditions. The asymmetric unit contains a disordered organic cation (occupancies in the ratio 0.72:0.28), a chloride anion and an MnCl(H(2)O) moiety with the Mn(II) atom...

The title compound, C(12)H(17)FNO(+)·Cl(-), is a degradation impurity of paroxetine hydro-chloride hemihydrate (PAXIL), an anti-depressant belonging to the group of drugs called selective serotonin reuptake inhibitors (SSRIs). Similar to the paroxetine hydro-chloride salt with protonation having taken place on the basic piperidine ring, the degradation impurity also exists as the hydro-chloride...
