Unique resonance Raman spectra were obtained when manganese(III) tetraphenylporphin halides in noncoordinating solvents were illuminated by laser frequencies around 500 nm. Of particular interest is the observation of a feature that is sensitive to the nature of the axial ligand. This feature disappears when the coordinating solvent pyridine is employed, and it, therefore, appears to be diagnos...

A novel 2D coordination polymer consisting of ferromagnetic Ni(ii) chains with alternating double EO-azide bridges and (EO-azide)bis(carboxylate) triple bridges exhibits solvent-modulated metamagnetism, and the reversible dehydration/hydration processes are accompanied by significant changes in critical temperature, critical field and hysteresis.

The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N4O2 octa-hedral coordination geometry is formed by two N,N'-chelating equatorial 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands and axially coordinating methanol coligands, resulting in the mononuclear trans-(N ...

In the title complex, [Cu(C(10)H(12)NO(4)S)(OH)(C(10)H(8)N(2))]·0.5H(2)O, the Cu(II) ion shows a distorted square-pyramidal coordination geometry with two N atoms from the 2,2'-bipyridine ligand and one N and one O atom from the N-tosyl-α-alaninato ligand forming the basis of the coordination polyhedron and another O atom of the hydroxo group acting as the apex of the pyramid. The solvent water...

In the title coordination polymer, {[Ag(8)(C(6)H(4)NO(2))(6)(NO(3))(2)]·0.5H(2)O}(n), two Ag(I) ions are two-coordinate within an AgN(2) set and six are three-coordinate within AgN(2)O and AgO(3) sets. The Ag-N and Ag-O distances are in the ranges 2.150 (5)-2.198 (5) and 2.142 (4)-2.702 (5) Å, respectively. A two-dimensional coordination network is formed parallel to (100). The O atom of the di...

In the crystal structure of the title compound, [CuCl(C(5)H(5)N)(4)][N(CN)(2)]·2C(6)H(5)N, the copper(II) cations are coordinated by one chloride anion and four N-bonded pyridine ligands into discrete complexes. The copper(II) cation shows a square-pyramidal coordination environment, with the chloride anion in the apical position. However, there is one additional chloride anion at 3.0065 (9) Å,...

In the title compound, [RhH(C74H68O8P2)(C18H15P)(CO)]·3C4H10O, the CHP3 coordination set at the Rh(I) ion is arranged in a distorted trigonal-bipyramidal geometry with the P atoms adopting equatorial coordination sites and the C atom of the carbonyl ligand as well as the H atom adopting the axial sites. The asymmetric unit contains two very similar mol-ecules of the rhodium complex, two half-oc...

In the structure of the title compound, [Pd(C(19)H(21)N(2)P)(2)](PF(6))(2)·2.85CH(3)CN, the two six-membered NHC-phosphane chelate rings form a distorted square-planar coordination geometry around the Pd(II) atom, which lies 0.212 (1) Å above the coordination plane. The sum of the bond angles at Pd(II) is 358.3°, with C-Pd-P bite angles of 84.03 (10) and 83.54 (9)°. The structure includes three...

The title compound, [Ru(C7F5O2)2(C10H14)(C21H24N2)]·2CH2Cl2, is formed as an orange crystalline powder by the reaction of RuCl2(p-cymene)(IMes) and AgOCOC6F5 in anhydrous tetra-hydro-furan (IMes = 1,3-dimesityl-2,3-di-hydro-1H-imidazol-2-yl-idene). The asymetric unit consists of two independent [Ru(C6F5COO)2(η(6)-p-cymene)(IMes)] com-plexes and four dichloro-methane solvent mol-ecules. In each ...
