Bis(2-amino-pyrimidine-?N)dibromidozinc(II).

ABSTRACT: The title compound, [ZnBr(2)(C(4)H(5)N(3))(2)], is a mononuclear complex in which the Zn(II) ions have distorted tetra-hedral coordination geometry. The Zn(II) ion binds to two N atoms from two different 2-amino-pyrimidine ligands and two bromide ions. N-H?N hydrogen bonds link the mol-ecules to form a one-dimensional supra-molecular structure. The supra-molecular chains are parallel to each other and N-H?Br hydrogen bonds link them into a two-dimensional network in the ac plane. Additionally, there are strong ?-? inter-actions [centroid-centroid distance = 3.403?(3)?Å].

Metal-nucleobase inter-action: bis[4-amino-pyrimidin-2(1H)-one-?N]dibromidozinc(II).

Project description:In the title complex, [ZnBr(2)(C(4)H(5)N(3)O)(2)], the central metal ion is coordinated to two bromide ions and endocyclic N atoms of the two cytosine mol-ecules leading to a distorted tetra-hedral geometry. The structure is isotypic with [CdBr(2)(C(4)H(5)N(3)O)(2)] [Muthiah et al. (2001). Acta Cryst. E57, m558-m560]. There are two inter-ligand N-H?Br hydrogen bonds, generating two hydrogen-bonded rings stabilizing the coordination sphere. The complex aggregates, forming supra-molecular chains, sheets and staircases through N-H?O and N-H?Br hydrogen bonding and ?-? stacking inter-actions [centroid-centroid distance = 3.616?(2)?Å].

Bis(?-4-amino-3,5-dimethyl-4H-1,2,4-triazole-?N:N)bis-(dibromidozinc).

Project description:The centrosymmetric dimeric title complex, [Zn(2)Br(4)(C(4)H(8)N(4))(2)], is isotypic with its [Zn(2)Cl(4)(C(4)H(8)N(4))(2)], [Zn(2)I(4)(C(4)H(8)N(4))(2)] and [Co(2)Cl(4)(C(4)H(8)N(4))(2)] analogues. The zinc atom is bonded to two N atoms belonging to triazole bridging rings and to two terminal bromide ligands, in a geometry close to tetra-hedral. Weak N-H?Br hydrogen bonds, with the amine functions as donor groups, are observed in the crystal structure, forming a three-dimensional supra-molecular network.

Bis(2-amino-pyrimidine-?N)aqua-(nitrato-?O)(nitrato-?O,O')zinc(II).

Project description:The water-coordinated Zn atom in the title monoaqua zinc nitrate adduct of 2-amino-pyrimidine, [Zn(NO(3))(2)(C(4)H(5)N(3))(2)(H(2)O)], is bonded to a monodentate nitrate ion and is chelated by the other nitrate ion. The heterocyclic ligands coordinate through ring N-donor sites. The coordination geometry about the Zn(II) atom is a distorted octa-hedron. Intra-molecular N-H?O hydrogen bonds occur. In the crystal, adjacent adduct mol-ecules are linked by O-H?O, O-H?N and N-H?O hydrogen bonds into a layer motif parallel to (001).

Project description:In the title compound, [Cd(NO(3))(2)(C(4)H(5)N(3))(2)(H(2)O)(2)]·H(2)O, the Cd atom is seven-coordinated by two 2-amino-pyrimidine mol-ecules, two water mol-ecules, one bidentate nitrate anion and one monodentate nitrate anion. A network of N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds helps to consolidate the crystal structure.

Diaqua-bis-(seleno-cyanato-?N)bis-(pyrimidine-?N)manganese(II).

Project description:In the crystal structure of the title compound, [Mn(NCSe)(2)(C(4)H(4)N(2))(2)(H(2)O)(2)], the manganese(II) cation is coordinated by two N-bonded pyrimidine ligands, two N-bonded seleno-cyanate anions and two O-bonded water mol-ecules in a distorted octa-hedral coordination mode. The asymmetric unit consists of one manganese(II) cation, located on a centre of inversion, as well as one seleno-cyanate anion, one water mol-ecule and one pyrimidine ligand in general positions. The crystal structure consists of discrete building blocks of composition [Mn(NCSe)(2)(pyrimidine)(2)(H(2)O)(2)], which are connected into layers parallel to (101) by strong water-pyrimidine O-H?N hydrogen bonds.

Bis[2-(methyl-amino)-troponato]copper(II).

Project description:In the title compound, [Cu(C(8)H(8)NO)(2)], a strictly square-planar geometry about the Cu(II) metal atom is observed. Substitution of an O atom with a methyl-functionalized N atom does not significantly alter the bond distances and angles in the copper(II) complex when compared with a similar bis-(troponato)copper(II) complex. ?-? stacking is observed between the tropolone rings, with inter-planar distances of 3.5039?(16) and 3.2933?(15)?Å, respectively. Additional stabilisation of the structure is accomplished through C-H?O hydrogen-bonding interactions.

Poly[tetra-?(1,1)-azido-bis-(?(2)-pyrimidine-2-carboxyl-ato)tricopper(II)].

Project description:In the title compound, [Cu(3)(C(5)H(3)N(2)O(2))(2)(N(3))(4)](n), one of the Cu(II) atoms lies on an inversion centre and is octa-hedrally coordinated by two bidentate chelating pyrimidine-2-carboxyl-ate ligands and two azide anions, each of which gives an N:N-bridge to the second inversion-related Cu(II) centre in the formula unit. The second Cu(II) atom is five-coordinated with a distorted square-pyramidal coordination sphere comprising a single bidentate chelating pyrimidine-2-carboxyl-ate anion and three azide N anions, two of which doubly bridge centrosymmetric Cu(II) centres, giving a two-dimensional network structure extending parallel to (010).
