Acta Crystallographica Section EStructure Reports Online was launched in January 2001 as the IUCr's first electronic-only journal. It is a rapid communication journal for the publication of concise reports on inorganic, metal-organic and organic structures, and benefits from an enhanced electronic publication procedure. Each published report includes a set of key indicators, giving a summary of the main descriptors of the precision and completeness of the study, with indications of problems such as disorder. The publication...Bis(2-bromopyridinium) hexachloridostannate(IV)- April 10, 2008 The asymmetric unit of the title compound, (C5H5BrN)2SnCl6, contains one cation and one half-anion. The SnCl62 anion is located on an inversion center and forms a quasi-regular octahedral arrangement. Hydrogen-bonding interactions of two kinds, viz. NH...ClSn and CH...ClSn, along with Cl...Br interactions 3.4393(15), connect the ions in the crystal structure into two-dimensional supramolecular arrays. These supramolecular arrays are arranged in layers approximately parallel to (110) built up...http://scripts.iucr.org/cgi-bin/paper?bh2165 (Carbonyl-1C)bis2,3(5)-cyclopentadienyl3-(S-methyl trithiocarbonato)methylidyne-1:2:34C,S:C:C(triphenylphosphine-1P)(3-sulfido-1:2:33S)dicobalt(II)iro- April 10, 2008 The asymmetric unit of the title compound, FeCo2(C5H5)2(C3H3S3)S(C18H15P)(CO)CF3SO3, consists of a triangular irondicobalt cluster cation and a trifluoromethanesulfonate anion. In the cation, the FeCo2 triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithiocarbonate residue that bridges the FeC bond. Each Co atom carries a cyclopentadienyl ligand while the Fe atom coordinates to one carbonyl and one triphenylphosphine ligand.

The crystal structure is stabilized by intermolecular NH...O hydrogen bonds, forming layers parallel to the bc plane.http://scripts.iucr.org/cgi-bin/paper?rz2202 Bis(-disulfur dinitrido)bisdiphenyltin(IV)- April 10, 2008 The title compound, Sn2(C6H5)4(N2S2)2, exists as a centrosymmetric binuclear dimer with the SnIV centres in distorted trigonal bipyramidal geometry and a central Sn2N2 core.http://scripts.iucr.org/cgi-bin/paper?bt2692 Bis2-acetyl-3-methylpyrazine (2-hydroxybenzoyl)hydrazonatozinc(II) monohydrate- April 10, 2008 In the title compound, Zn(C14H13N4O2)2H2O, the ZnII centre is six-coordinated by four N and two O donors of two 2-acetyl-3-methylpyrazine (2-hydroxybenzoyl)hydrazonate ligands, and forms a distorted octahedral structure.http://scripts.iucr.org/cgi-bin/paper?at2559 (2,2-Bipyridine-2N,N)iodido(pyrrolidine-1-dithiocarboxylato-2S,S)copper(II)- April 10, 2008 In the title compound, Cu(C5H8NS2)I(C10H8N2), the CuII ion is coordinated by one iodide ion, two N atoms of the bipyridine ligand and two S atoms from the pyrrolidine-1-dithiocarboxylate ligand in a distorted square-pyramidal environment.http://scripts.iucr.org/cgi-bin/paper?at2555 Bis4-(Z)-(4-fluorobenzylamino)(phenyl)methylene-3-methyl-1-phenyl-1H-pyrazol-5(4H)-onato-2N4,Onickel(II)- April 10, 2008 The molecule of the title compound, Ni(C24H19FN3O)2, has twofold rotation symmetry. The NiII ion is in a square-planar coordination geometry which is distorted towards tetrahedral and is coordinated by two N atoms of imine and two O atoms of pyrazolone from two Schiff base 4-(Z)-(4-fluorobenzylamino)phenylmethylene-3-methyl-1-phenyl-1H-pyrazol-5(4H)-onate ligands.http://scripts.iucr.org/cgi-bin/paper?lx2051 Bis-2,2-(3-azapentane-1,5-diyl)bis(nitrilomethylidyne)diphenolatodicopper(II) dimethyl sulfoxide disolvate- April 10, 2008 The title compound, Cu2(C18H19N3O2)22C2H6OS or Cu2(SalenN3H)22DMSO, where SalenN3H is the multidentate Schiff base 2,2-(3-azapentane-1,5-diyl)bis(nitrilomethylidyne)diphenolate dianion and DMSO is dimethyl sulfoxide, is a solvated dinuclear CuII complex. The neutral complex is built from two Cu(SalenN3H) units related by an inversion center. All heteroatoms in the Schiff bases coordinate the CuII ions, which display highly distorted trigonal bipyramidal geometries.
