Poly[[diaquahemi-μ4-oxalato-μ2-oxalato-praseodymium(III)] monohydrate]
In the title complex, {[Pr(C(2)O(4))(1.5)(H(2)O)(2)]·H(2)O}(n), the Pr(III) ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr-O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occup...
متن کاملPyridine-2-carboximidamidate chloride monohydrate
The title compound, C(6)H(8)N(3) (+)·Cl(-)·H(2)O, crystallizes with three formula units in the asymmetric unit. The cations are non-planar with the -C(NH(2))(2) groups twisted out of the ring planes. Each pyridine carboximidamidate cation is linked to another cation through N-H⋯N hydrogen bonds, to chloride ions by N-H⋯Cl hydrogen bonds, and to water mol-ecules by N-H⋯O hydrogen bonds. Water mo...
متن کامل2-(Mesitylmethylsulfanyl)pyridine N-oxide monohydrate
In the title compound, C(15)H(17)NOS·H(2)O, the benzene and pyridine rings form a dihedral angle of 71.18 (2)°. The intra-molecular S⋯O distance [2.737 (3) Å] is shorter than expected and, in terms of hybridization principles, the N-C-S angle [114.1 (2)°] is smaller than expected. The crystal structure is stabilized by inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds. In addition, weak π-π s...
متن کامل2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate
The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...
متن کاملcatena-Poly[[(pyridine-κN)copper(II)]-μ3-pyridine-2,6-dicarboxylato-κ3 O 2:O 2′,N,O 6:O 6′]
In the title compound, [Cu(C(7)H(3)NO(4))(C(5)H(5)N)](n), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensiona...
