Computational resources from cluster environments have become a key component in many organizations. Scientific, industrial and commercial applications are more dependent from a cluster performance. In this context, high availability of clusters is a challenge research subject. The OSCAR (Open Source Cluster Application Resource) software environment is an(More)
The structures of three related complexes of general formula M(pds)(nab)2 [pds is the peroxodi-sulfate anion and nab is an nitro-gen-containing aromatic base], viz. bis(2,9-dimethyl-1,10-phenanthroline-κ2N,N')(peroxodi-sulfato-κ2O,O')cadmium, [Cd(S2O8)(C14H12N2)2], (V), bis-(3,4,7,8-tetra-methy-1,10-phenanthroline-κ2N,N')(peroxodi-sulfato-κ2O,O')zinc,(More)
The centrosymmetric dinuclear complex bis-(μ-3-carb-oxy-6-methyl-pyridine-2-carboxyl-ato)-κ(3) N,O (2):O (2);κ(3) O (2):N,O (2)-bis-[(2,2'-bi-pyridine-κ(2) N,N')(nitrato-κO)cadmium] methanol monosolvate, [Cd2(C8H6NO4)2(NO3)2(C10H8N2)2]·CH3OH, was isolated as colourless crystals from the reaction of Cd(NO3)2·4H2O, 6-methyl-pyridine-2,3-di-carb-oxy-lic acid(More)
The asymmetric unit of the title compound, C8H9NO2·H2O consists of an isolated 4-(ammonio-meth-yl)benzoate zwitterion derived from 4-amino-methyl-benzoic acid through the migration of the acidic proton, together with a water molecule of crystallization that is disordered over three sites with occupancy ratios (0.50:0.35:0.15). In the crystal structure,(More)
4,4'-(Disulfanediyl)dibutanoic acid (dtba) and 4,4'-bipyridine (4,4'-bpy) crystallize in an 1:1 ratio, leading to the title co-crystal with composition C8H14O4S2·C10H8N2. A distinctive feature of the crystal structure is the geometry of the dtba moiety, which appears to be stretched [with a 9.98 (1) Å span between outermost carbons] and acts as an(More)
The asymmetric unit of the title complex, [Ni(C12H8N2)3]S2O8·2C3H7NO·H2O, consists of a complex [Ni(phen)3](2+) cation and one isolated pds anion, with two DMF mol-ecules and one water mol-ecule as solvates (where phen is 1,10-phenanthroline, pds is the hexa-oxido-μ-peroxoido-di-sulf-ate dianion and DMF is dimethyl-formamide). The [Ni(phen)3](2+) cation is(More)
The mol-ecular structure of the title compound, [Zn(CH(3)COO)(2)(C(12)H(12)N(2))], consists of isolated mol-ecules bis-ected by a twofold rotation axis which goes through the Zn(II) cation and halves the organic base through the central C-C bond. The Zn(II) ion is coordinated by two N atoms from one mol-ecule of the aromatic base and four O atoms from two(More)
The mol-ecular structure of the title compound, NH(4) (+)·C(7)H(7)O(4)S(-), is featureless [the methoxy C atom deviating 0.173 (6) Å from the phenyl mean plane] with inter-atomic distances and angles in the expected ranges. The main feature of inter-est is the packing mode. Hydro-philic (SO(3) and NH(4)) and hydro-phobic (PhOCH(3)) parts in the structure(More)
The title Nd complex [Nd(2)(C(4)H(5)O(2))(6)(H(2)O)(4)]·2C(5)H(6)N(6) is isotypic with two previously reported Dy and Ho isologues. It is composed of [Nd(crot)(3)(H(2)O)(2)](2) dimers [crot(onate) = but-2-enoate = C(4)H(5)O(2)], built up around symmetry centres and completed by 2,6-diamine-purine mol-ecules acting as solvates. The neodymium cations are(More)
