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

ABSTRACT: 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.

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.

Project description:In the title compound, [Zn(2)I(4)(C(4)H(8)N(4))(2)], the Zn(II) atom is coordinated in a distorted tetra-hedral geometry by two N atoms from the triazole rings of two 4-amino-3,5-dimethyl-4H-1,2,4-triazole (admt) ligands and two iodide ligands.

Project description:In the mol-ecular structure of the centrosymmetric mononuclear complex [Ni(2-bpt)(2)(H(2)O)(2)](ClO(4))(2) [2-bpt = 4-amino-3,5-di-2-pyridyl-1,2,4-triazole, (C(12)H(10)N(6))], the central Ni(II) atom is six-coordinated by a pair of chelating 2-bpt ligands and two water mol-ecules. Inter-molecular O-H⋯N inter-actions link the monomeric units into a two-dimensional hydrogen-bonded (4,4) network, which is extended to a three-dimensional supra-molecular aggregate via π⋯π stacking inter-actions [centroid-centroid distances 3.809 (3) and 3.499 (3) Å].

4-Amino-3,5-di-2-pyridyl-4H-1,2,4-triazole.

Project description:In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.

Project description:The title complex, [Ni(2)(C(4)H(8)N(4)O(2))(6)](NO(3))(4)·2CH(4)O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis-(hydroxy-meth-yl)-1,2,4-triazole ligands. The separation between the Ni(II) atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octa-hedral coordination. Inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the ligands, solvent mol-ecules and nitrate ions.

Project description:In the title homochiral mononuclear compound, [Zn(NO(3))(2)(C(6)H(12)N(4)O(2))(2)], the Zn(II) atom is located on a twofold rotation axis and coordinated by two N atoms from two ligands and two O atoms from two NO(3) (-) anions, adopting a distorted tetra-hedral coordination geometry. The compound is enanti-omerically pure and corresponds to the S diastereoisomer, with the optical activity originating from the chiral ligand. In the crystal, mol-ecules are connected into three-dimensional supra-molecular networks through O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds.

Bis(?-3,5-dimethyl-4H-1,2,4-triazol-4-amine-?N:N)bis-[bis-(thio-cyanato-?N)zinc]-bis-(3,5-dimethyl-4H-1,2,4-triazol-4-amine-?N)bis-(thio-cyanato-?N)zinc (1/2).

Project description:In the crystal structure of the title 1:2 adduct, [Zn(2)(NCS)(4)(C(4)H(8)N(4))(2)]·2[Zn(NCS)(2)(C(4)H(8)N(4))(2)] or (Ia)·2(Ib), each Zn(II) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two triazole rings of two 4-amino-3,5-dimethyl-1,2,4-triazole (admt) ligands and two NCS(-) ligands. In (Ia), double N(1):N(2)-bridging admt ligands connect two Zn(II) atoms, forming a dimer with a Zn(2)(admt)(2) six-membered metallacycle located on a crystallographic inversion center. In (Ib), the admt ligands exhibit monodentate N(1)-coordination modes. Weak N-H?N, N-H?S and C-H?S hydrogen bonds play an important role in the inter-molecular packing. The S and C atoms of two thiocyanato ligands are disordered over two sets of sites in ratios of 0.57?(3):0.43?(3) and 0.63?(3):0.37?(3), respectively.

Bis(?(2)-3,5-diisopropyl-4H-1,2,4-triazole-?N:N)bis-[(nitrato-?O)silver(I)].

Project description:The neutral N-heterocycle in the title centrosymmetric dinuclear compound, [Ag(2)(NO(3))(2)(C(8)H(15)N(3))(2)], bridges two metal atoms through its imino N atoms. The N-Ag-N skeleton is bent [N-Ag-N = 127.2?(3)°]; as one of two O atoms of the nitrate anion is nearly coplanar with this N-Ag-N skeleton [Ag-O = 2.63?(1)?Å], the coordination geometry around the Ag(I) atom is regarded as trigonal-planar. One of the two isopropyl groups is disordered over two positions in respect of the methyl groups in a 1:1 ratio. In the crystal structure, inter-molecular N-H?O hydrogen bonding is observed between the nitrate groups and triazole ligands.
