Bis[3-dimethyl-amino-1-(pyridin-2-yl)prop-2-en-1-one-κN,O]tris-(nitrato-κO,O)gadolinium(III) ethanol disolvate.

In the title compound, [Gd(NO(3))(3)(C(10)H(12)N(2)O)(2)]·2C(2)H(5)OH, the Gd(III) ion and one nitrate anion are located on a twofold rotation axis. The Gd(III) ion is ten-coordinated by two N and two O atoms from two bidentate 3-(N,N-dimethyl-amino)-1-(2-pyrid-yl)prop-2-en-1-one) ligands and six O atoms from three nitrate anions in a distorted bicapped square-anti-prismatic geometry. In the crystal, the components are linked by O-H⋯O hydrogen bonds.

Bis{3-[2-(methyl-sulfon-yl)pyrimidin-4-yl]pyridinium} tetra-chloridocadmium.

In the title compound, (C(10)H(10)N(3)O(2)S)(2)[CdCl(4)], the Cd(II) ion lies on a twofold axis and is coordinated by four chloride anions, with bond distances of 2.4787 (10) and 2.4410 (10) Å.

Poly[aqua-bis-[μ(3)-4-(3-pyrid-yl)pyrimidine-2-sulfonato-κN:N,O:O][μ(2)-4-(3-pyrid-yl)pyrimidine-2-sulfonato-κN:N,O]tris-ilver(I)].

In the crystal structure of the title compound, [Ag(3)(C(9)H(6)N(3)O(3)S)(3)(H(2)O)(2)](n), the mol-ecules are linked into three-decked polymeric zigzag chains propagating in [100]. On the middle deck, the Ag atom is five-coordinated by three O atoms from three 4-(3-pyrid-yl)pyrimidine-2-sulfonate (L) ligands, one of which lies on a mirror plane with the sulfonate group disordered over two orientations in a 1:1 ratio, and two N atoms from two L ligands, which lie on the same mirror plane. On the upper and lower decks, the Ag atom is four-coordinated by an aqua ligand, one O and two N atoms from two L ligands with the pyridyl and pyrimidine rings twisted at 19.

Bis[3-dimethyl-amino-1-(2-pyrid-yl)prop-2-en-1-one-κN,O]tris-(nitrato-κO,O')praseodymium(III).

In the title compound, [Pr(NO(3))(3)(C(10)H(12)N(2)O)(2)], the Pr(III) ion is ten-coordinated by two N and two O atoms from two bidentate 3-(dimethyl-amino)-1-(2-pyrid-yl)prop-2-en-1-one ligands and by six O atoms from three nitrate anions in a distorted bicapped square-anti-prismatic geometry. An extensive three-dimensional network of weak inter-molecular C-H⋯O hydrogen bonds consolidates the crystal packing.
