Bis[4-(dimethyl-amino)-pyridinium] octa-aqua-chloridolanthanum(III) tetra-chloride trihydrate.

ABSTRACT: The title organic-inorganic salt, (C(7)H(11)N(2))(2)[LaCl(H(2)O)(8)]Cl(4)·3H(2)O, consists of two 4-(dimethyl-amino)-pyridinium and one [La(H(2)O)(8)Cl](2+) cations, four chloride anions and three solvent water mol-ecules. In the crystal, the various units are connected by N-H⋯Cl, O-H⋯Cl, O-H⋯O and N-H⋯O hydrogen bonds, forming a network of alternating organic and inorganic layers. The 4-(dimethyl-amino)-pyridinium cations stack along the c axis, while the inorganic layers lie parallel to the ac plane. The chloride anions are located between these entities, forming hydrogen bonds with the NH atom of the pyridinium ions and the water mol-ecules. There are also C-H⋯Cl hydrogen bonds present involving one of the 4-(dimethyl-amino)-pyridinium cations, resulting in the formation of a three-dimensional supra-molecular architecture.

4-(Dimethyl-amino)-pyridinium octa-aqua-erbium(III) tetra-chloride monohydrate.

Project description:In the title compound, (C(7)H(11)N(2))[Er(H(2)O)(8)]Cl(4)·H(2)O, the asymmetric unit consists of one 4-(dimethyl-amino)-pyridinium and one octa-aqua-erbium cation balanced by four Cl(-) anions, and one water mol-ecule. The 4-(dimethyl-amino)-pyridinium cation is protonated at the pyridine N atom. The dimethyl-amino group (C/N/C) lies close to the plane of the pyridinium ring, making a dihedral angle of 4.5?(3)°. In the crystal, the [Er(H(2)O)(8)](3+) cations are linked via O-H?O and O-H?Cl hydrogen bonds, forming two-dimensional networks propagating in the ab plane. These networks are linked via O-H?O and O-H?Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethyl-amino)-pyridinium cations are located in the cavities and are linked to the framework via N-H?Cl, C-H?O and C-H?Cl hydrogen bonds.

Bis[4-(dimethyl-amino)-pyridinium] tetra-chloridozincate.

Project description:In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and π-π stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H⋯Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network. Within the network, inter-molecular π-π stacking inter-actions with a centroid-centroid distance of 3.5911 (7) Å arrange the 4-(dimethyl-amino)-pyridinium cations into anti-parallel dimers.

Project description:The title compound, (C(7)H(11)N(2))(3)[Nd(2)Cl(4)(H(2)O)(10)]Cl(5)·2H(2)O, consists of three 4-(dimethyl-amino)-pyridinium cations, one of which is disordered about an inversion center, one [Nd(2)Cl(4)(H(2)O)(10)](2+) dication possessing inversion symmetry, five chloride anions, one of which is disordered over two inversion centers, and two lattice water mol-ecules. The 4-(dimethyl-amino)-pyridinium cations are protonated at the pyridine N atoms and form N-H?Cl hydrogen bonds with Cl(-) counter-ions. The dimethyl-amino groups (C/N/C) lie close to the plane of the pyridinium rings, making dihedral angles of 1.6?(6)° and 6.5?(3)°.

These sheets are linked via O-H?Cl hydrogen bonds, forming a three-dimensional network.

Project description:In the crystal structure of the title compound, (C7H11N2)2[Mn(NCS)4(C7H10N2)2], the manganese(II) cations are coordinated by four N-bonded thio-cyanate anions and two N-bonded 4-(dimethyl-amino)-pyridine ligands into discrete complex dianions.
