1-(2-Bromophenyl)ethane-1,2-diyl 1,1′-biphenyl-2,2′-dicarboxylate
In the title compound, C(22)H(15)BrO(4), the bromo-benzene ring is inclined at dihedral angles of 23.87 (11) and 52.37 (11)° with respect to the planes of the two benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 49.08 (11)°. In the crystal, mol-ecules are linked into [100] chains by C-H⋯O hydrogen bonds.

The title compound, C(32)H(24)N(6)O(2), has an inversion centre located at the mid-point of the central C-C bond of the diether bridging unit. The terminal pyridine rings are canted relative to the central pyridine ring, with dihedral angles of 12.98 (6) and 26.80 (6)°. The maximum deviation from the eight-atom mean plane, defined by the two bridging O and C atoms and the central pyridine ring,...

attracted considerable attention in recent years due to their diverse structural possibilities and relevance in materials science.1–3 Mononuclear cis complexes, [M(ER)2L2], are useful precursors for the synthesis of biand poly-nuclear complexes.2,3 These complexes are usually derived from simple organochalcogenolate ions. Internally functionalized organochalcogenolates, such as 2-selenopyridina...

The title compound, C(5)H(4)N(10)·H(2)O, is composed of three five-membered rings that are essentially coplanar, the dihedral angles between the imidazole ring and the tetra-zole rings being 3.5 (2) and 3.0 (2)°. In the crystal, inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds lead to the formation of a three-dimensional network. An intra-molecular N-H⋯N hydrogen bond is also present.
متن کاملCrystal structure of di-μ-hydroxido-κ4 O:O-bis[bis(acetylacetonato-κ2 O,O′)cobalt(III)]
The dinuclear title complex, [Co2(C5H7O2)4(μ-OH)2] or [Co(acac)2(μ-OH)]2, where acac is acetyl-acetonate, is centrosymmetric with half of the mol-ecule per asymmetric unit. The mol-ecular structure is a dimer of octa-hedrally coordinated Co(III) atoms with four O atoms from two chelating acac ligands and two O atoms from bridging hydroxide ligands. The crystal packing features weak C-H⋯O inter-...
