There are independent cations and four chloride anions in the crystal structure of the title complex, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)]Cl(2). In each cation, the Co(II) cation is coordinated by four N atoms from two biimidazole and two O atoms of two water mol-ecules; one Co atom is at a position of site symmetry m, the other at a position of site symmetry 2/m. All Cl(-) ions and water mol-ecules...

The title compound, C24H19ClN2, crystallizes with two independent mol-ecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two mol-ecules. The 4-and 5-substituted phenyl rings and the benzene ring make dihedral angles of 67.06 (8), 5.61 (8) and 41.09 (8)°, respectively, with the imadazole ring in one mol-ecule and 71.53 (8), 28.85...

The present manuscript deals with detailed molecular interactions crystal structure. Its space group is P-1 the unit cell parameters: = 8.9164(7), b 9.7058(9), c 17.7384(12) Å, α 88.308(7)°, β 89.744(6)°...

The structure of the title compound, C(7)H(9)NO(2)S, was previously determined from powder diffraction data [Tremayne, Seaton & Glidewell (2002). Acta Cryst. B58, 823-834]. It has now been refined to a significantly higher precision. The amino N-atom is bent with a C-C-S-N torsion angle of -65.8 (2)deg;. In the crystal, mol-ecules are packed into a three-dimensional framework/supramolecular str...

In the crystal structure of the title compound, C8F16I2·C14H8N2, the mol-ecules form infinite chains parallel to [2-11] through two symmetry-independent C-I⋯N halogen bonds (XBs). As commonly found, the perfluoro-alkyl mol-ecules segregate from the hydro-carbon ones, forming a layered structure. Apart from the XBs, the only contact below the sum of van der Waals radii is a weak H⋯F contact. The...

In the title methanol disolvate complex, [Ni(4)(C(14)H(16)N(3)O(4))(2)(ClO(4))(2)(C(10)H(8)N(2))(2)]·2CH(3)OH, the neutral tetra-nickel(II) system lies on a centre of inversion. The polyhedron around each Ni(II) atom is a square pyramid. The separations of the Ni atoms bridged by the oxamide and carboxyl groups are 5.227 (9) and 5.268 (6) Å, respectively. In the crystal structure, a two-dimensi...

the structure of the nonaaquayttrium (iii) bromate, [y(h2o)9](bro3)3, at low temperature (100 k) has been studied by means of single-crystal x-ray diffraction. crystallography shows a hexagonal unit cell, space group p63/mmc (no. 194) with z = 2, a = b = 11.7104(11) å, c = 6.6259(5) å and v = 786.90(12) å3 at 100 k. the hydrated trivalent yttrium(iii) ion forms a tricapped trigonal prism, in wh...

The single crystals of tetrameric [Me3Sn(PhN2O2)]4 (1) supramolecule demethylates into single crystals of [Me2Sn(PhN2O2)2]2 dimer (2) and volatile Me4Sn, as a result of a crystal-to-crystal supramolecular structural transformation, which occurs upon heating and it is accompanied by a significant change of the molecular and crystal structures.

The crystal structure of the title Schiff base complex is obtained by single-crystal X-ray diffraction data.The solid state structure determination reveals that the coordination geometry around the copper(II) center istetrahedrally distorted square-planar. The crystal packing shows one dimensional infinite chains which arisesfrom the intermolecular interaction and stabilize the crystal packing.

A novel three-dimensional metal-organic framework (MOF), Ag4(tpt)4{δ-[Mo8O26]}·1.5H2O (A) (tpt = 2,4,6-tris(4-pyridyl)-1,3,5-triazine), possesses a ths-type topology with the hinge deformation mode. The single-crystal X-ray diffraction study shows that A and the dehydrated phase Ag4(tpt)4{δ-[Mo8O26]} (B) display distinct anisotropic thermal expansion with expansion in the b direction but contra...
