Bis(2,2'-bipyrid-yl)bromidocopper(II) bromide bromo-acetic acid hemihydrate.

ABSTRACT: In the title compound, [CuBr(C(10)H(8)N(2))(2)]Br·BrCH(2)COOH·0.5H(2)O, the Cu(II) ion is coordinated by four N atoms [Cu-N = 1.985 (6)-2.125 (7) Å] from two 2,2'-bipyridine ligand mol-ecules and a bromide anion [Cu-Br = 2.471 (2) Å] in a distorted trigonal-bipyramidal geometry. Short centroid-centroid distances [3.762 (5) and 3.867 (5) Å] between the aromatic rings of neighbouring cations suggest the existence of π-π inter-actions. Inter-molecular O-H⋯Br hydrogen bonds and weak C-H⋯O and C-H⋯Br inter-actions consolidate the crystal packing.

Project description:In the title complex, [Co(NCO)(2)(C(10)H(8)N(2))(2)], the Co atom is coordinated by four N atoms from two 2,2'-bipyridyl ligands and two N atoms from two cyanate anions in a distorted octa-hedral geometry.

Hexa-μ(2)-benzoato-bis-(2,2'-bipyrid-yl)trimanganese(II) monohydrate.

Project description:The complex molecule of the title compound, [Mn(3)(C(7)H(5)O(2))(6)(C(10)H(8)N(2))(2)]·H(2)O, contains a linear array of divalent manganese ions. The central Mn(II) atom, which is located on a crystallographic inversion center, is coordinated octa-hedrally by six benzoate O atoms. The two terminal Mn(II) ions are six-coordinated by four benzoate O atoms and two N atoms of 2,2'-bipyridyl. The central Mn(II) atom and the terminal Mn(II) ions are bridged by four benzoate ligands in a bidentate fashion, whereas the other two carboxyl-ate ligands form bridges through one O atom only and chelate the terminal Mn(II) atom. The mol-ecules pack together via van der Waals attractions and C-H⋯O hydrogen bonds.

Bis(μ-5-carboxyl-atotetra-zolido)bis-[aqua-(2,2'-bipyrid-yl)cadmium(II)].

Project description:In the title dinuclear Cd(II) complex, [Cd(2)(C(2)N(4)O(2))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], each Cd atom is in a slightly distorted octa-hedral coordination by two N atoms and one O atom of two 1H-tetra-zole-5-carboxyl-ate (TZC) ligands, two N atoms of a 2,2'-bipyridyl ligand and one water O atom. The TZC ligand acts in a tridentate N,O-chelating N-bridging mode to two symmetry-equivalent Cd(II) atoms. The complex reveals mol-ecular C(i) symmetry. Extensive O-H⋯O hydrogen bonding plays an important role in the crystal packing.

(2,2'-Bipyrid-yl)bis-[N,N-bis-(2-hydroxy-ethyl)dithio-carbamato-κS,S']cadmium(II).

Project description:The title compound, [Cd(C(5)H(10)NO(2)S(2))(2)(C(10)H(8)N(2))], features a trigonal-prismatic coordination geometry for the Cd(II) ion, based on an N(2)S(4) donor set defined by two chelating dithio-carbamate ligands and a 2,2'-bipyridyl ligand. In the crystal, extensive O-H⋯O hydrogen bonding results in the formation of 12-membered {⋯HO}(6) synthons and one-dimensional supra-molecular chains with further O-H⋯S inter-actions providing additional stability to the linear chain with base vector [01].

cyclo-Tetra-kis{μ-2,2'-dimethyl-1,1'-[2,2-bis-(bromo-meth-yl)propane-1,3-di-yl]di(1H-benzimidazole)-κN:N}tetra-kis-[bromidocopper(I)].

Project description:The title compound, [Cu(4)Br(4)(C(21)H(22)Br(2)N(4))(4)], features a macrocyclic Cu(4)L(4) ring system in which each Cu(I) atom is coordinated by one bromide ion and two N atoms from two 2,2'-dimethyl-1,1'-[2,2-bis-(bromo-meth-yl)propane-1,3-di-yl]di(1H-benzimidazole) (L) ligands in a distorted trigonal-planar geometry. The L ligands adopt either a cis or trans configuration. The asymmetric unit contains one half-mol-ecule with the center of the macrocycle located on a crystallographic center of inversion. Each bromide ion binds to a Cu(I) atom in a terminal mode and is oriented outside the ring. The macrocycles are inter-connected into a two-dimensional network by π-π inter-actions between benzimid-azole groups from different rings [centroid-centroid distance = 3.803 (5) Å.

Bis-(2-bromo-eth-yl)ammonium bromide.

Project description:The title salt, C(4)H(10)Br(2)N(+)·Br(-), crystallizes with four cations and four anions in the asymmetric unit. In the crystal, the bis-(2-bromo-eth-yl)ammonium cations and bromide anions are linked into chains by N-H⋯Br hydrogen bonds describing a binary C(2) (1)(4) motif along [010]. Each of these chains is formed by a unique cation and anion pair. The ammonium cations occur in the less preferred anti conformation, characterized by different NCCBr torsion angles. Adjacent chains are linked by weak C-H⋯Br inter-actions, forming a three-dimensional network. The crystal studied was a pseudo-merohedral twin with twin ratio 0.640 (2):0.360 (2).
