Topological analysis of the three-dimensional coordination polymer poly[(μ4-azido)[μ4-5-(pyridin-4-yl)tetrazolido]disilver(I)].

The title compound, [Ag2(C6H4N4)(N3)]n, was obtained under hydrothermal conditions at 433 K. The asymmetric unit of the orthorhombic space group (Pna21) consists of two Ag(+) cations, an anionic 5-(pyridin-4-yl)tetrazolide (4-ptz(-)) ligand and an anionic azide ligand. Both Ag(+) centres are coordinated by four N atoms, forming a distorted tetrahedral coordination environment.

The three-dimensional coordination network in poly[di-μ3-cyanido-μ5-[5-(pyridin-4-yl)tetrazolato]-tricopper(I)].

In the title three-dimensional tetrazolate-based coordination polymer, poly[bis(μ(3)-cyanido-κ(3)N:C:C)[μ(5)-5-(pyridin-4-yl)tetrazolato-κ(5)N:N':N'':N''':N'''']tricopper(I)], [Cu(3)(C(6)H(4)N(5))(CN)(2)](n), there are two types of coordinated Cu(I) atoms. One type exhibits a tetrahedral environment and the other, residing on a twofold axis, adopts a trigonal coordination environment. The closest Cu···Cu distance is only 2.

Benzene-1,3,5-tricarb-oxy-lic acid-5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetra-zol-5-ide (1/1).

The asymmetric unit of the title compound, C(6)H(5)N(5)·C(9)H(6)O(6), comprises a full mol-ecule each of neutral trimesic acid (tma) and zwitterionic 5-(pyridin-1-ium-3-yl)-5H-1,2,3,4-tetra-zol-5-ide (ptz). The components are linked into a two-dimensional layer by a combination of O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds parallel to the (10[Formula: see text]) plane. Layers comprising alternating rows of tma and ptz are linked into a three-dimensional network by C-H⋯O and π-π inter-actions between tma and tetra-zolate rings [centroid-centroid distance = 3.

Two-dimensional networks in 2-methylanilinium picrate and 2,5-dichloroanilinium picrate.

Both the title molecular adducts of 2-methylaniline or 2,5-dichloroaniline with picric acid are 1:1 organic salts, namely 2-methylanilinium picrate, C(7)H(10)N(+) x C(6)H(2)N(3)O(7)(-), (I), and 2,5-dichloroanilinium picrate, C(6)H(6)Cl(2)N(+) x C(6)H(2)N(3)O(7)(-), (II). In both structures, the phenoxide O atoms accept two N-H hydrogen bonds in a bifurcated acceptor fashion, which link the component ions by N-H..
