In the title mol-ecule, C(7)H(7)N(5)S, the pyridyl and triazole rings form a dihedral angle of 20.07 (6)°. Inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains extended in the direction [10]. Further stability is provided by π⋯π stacking inter-actions, indicated by short distances between the centroids of triazole rings [3.480 (5) Å] and pyridyl rings [3.574 (5) Å] of neighbouri...

The asymmetric unit of the title compound, C(17)H(25)NO(7)S, contains two independent mol-ecules, which are enanti-omers forming a hydrogen-bonded dimer associated with two R(2) (2)(7) patterns. In each mol-ecule, one ethyl group from the two available ethyl ester functional groups is disordered. In one mol-ecule, the ethyl group of the ester function from an α-carb-oxy-lic acid is positionally...

In the title complex, [Mn(C(4)H(5)O(2))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is seven-coordinated in a distorted monocapped trigonal-prismatic geometry formed by a tetra-dentate tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine mol-ecule, a bidentate 2-methacrylate anion and a dimethyl-formamide mol-ecule. The methyl groups of the coordinated dimethyl-formamide mol-ecule...

The asymmetric unit of the title compound, C(15)H(17)NO(2), contains two independent mol-ecules in which the dihedral angles between the pyrrole and benzene rings are 42.43 (9) and 45.70 (9)°. In both mol-ecules, the but-oxy chains are disordered over two sets of sites, with occupancy ratios of 0.701 (7):0.299 (7) and 0.869 (4):0.131 (4). Each mol-ecule forms a dimer with an inversion-related m...

Mol-ecules of the title compound [ZnCl(2)(C(7)H(7)NO(2))(2)], are located on a twofold rotation axis. Two 4-amino-benzoic acid moieties, and two chloride ligands are coordinated to a Zn atom in a tetra-hedral fashion, forming an isolated mol-ecule. Neighbouring mol-ecules are linked through hydrogen-bonded carboxyl groups, as well as N-H⋯Cl hydrogen-bonding inter-actions between amine groups an...

In the title compound, [Mn(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·2C(3)H(7)NO, the central Mn(II) ion, located on an inversion center, is hexa-coordinated by four O atoms from two water mol-ecules and two carboxyl-ate groups, and two N atoms from two 4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ate anions in a slightly distorted octa-hedral environment. The complex mol-ecules and solvent mol-ecules are ...

In the title compound, [Ca(C(15)H(9)O(7)S)(H(2)O)(6)](C(15)H(9)O(7)S)·3H(2)O, the Ca centre has a distorted deca-hedral geometry, coordinated by six O atoms from water mol-ecules and one sulfonate O atom. The crystal structure is stabilized by aromatic π-π inter-actions, with centroid-centroid distances of 3.765 (5) and 3.896 (5) Å between the phenyl ring and the benzene ring of the chromene un...
