Ammonium tris-(3-amino-pyrazine-2-carboxyl-ato-?N,O)nickelate(II) trihydrate.

ABSTRACT: The Ni(II) atom in the title hydrated salt, (NH(4))[Ni(C(5)H(4)N(3)O(2))(3)]·3H(2)O, is N,O-chelated by the three 3-aminopyrazine-2-carboxyl-ate ligands, resulting in a distorted octa-hedral mer-NiN(3)O(3) geometry for the metal. In the crystal, the complex anion, ammonium cation and uncoordinated water mol-ecules are linked by extensive N-H?N, N-H?O, O-H?N and O-H?O hydrogen bonds, forming a three-dimensional network.

The Ni(II) atom in the title hydrated salt, (NH(4))[Ni(C(5)H(4)N(3)O(2))(3)]·3H(2)O, is N,O-chelated by the three 3-aminopyrazine-2-carboxyl-ate ligands, resulting in a distorted octa-hedral mer-NiN(3)O(3) geometry for the metal. In the crystal, the complex anion, ammonium cation and uncoordinated water mol-ecules are linked by extensive N-H⋯N, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming a three-dimensional network. ...[more]

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, the Ag(I) and Ni(II) ions lie on a mirror plane and an inversion centre, respectively. The complex chains, the nitrate ions and the uncoordinated water mol-ecules are linked together through O-H?O hydrogen bonds and weak Ag?O inter-actions [2.619?(17)-2.749?(17)?Å] into a three-dimensional network.

Poly[aqua-(?-pyrazine-2-carboxyl-ato-?N,O:O)(?-pyrazine-2-carboxyl-ato-?N,O:O')lead(II)].

Project description:The polymeric structure of the title compound, [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](n), is built up from centrosymmetric [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](2) dimers, which are bridged by ligand carboxyl-ate O atoms. The Pb(II) ion adopts an irregular PbN(2)O(5) coordination polyhedron; it is chelated by one N,O-bidentate ligand and also bonds to a water O atom. A second N,O-bidentate ligand forms the dimer bridge and another bridging O atom from a nearby dimer also bonds to the Pb(II) ion, leading to layers propagating in (100). A network of O-H?O hydrogen bonds operates between water O atoms (donors) and carboxyl-ate O atoms (acceptors).

Bis(9-amino-acridinium) bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)nickelate(II) trihydrate.

Project description:The title compound, (C(13)H(11)N(2))(2)[Ni(C(7)H(3)NO(4))(2)]·3H(2)O, consists of a mononuclear anionic complex, two 9-amino-acridinium cations and three uncoordinated water mol-ecules. Two pyridine-2,6-dicarboxyl-ate (pydc) ligands are bound to the Ni(II) ion, giving an NiN(2)O(4) bonded set. The coordination geometry around the Ni(II) atom is distorted octa-hedral. There are two types of robust O-H?O hydrogen-bond synthons, namely R(6) (6)(24) and R(2) (4)(8), which link the complex anions and water mol-ecules to each other. N-H?O hydrogen bonds connect the stacks of anions and cations in the structure. Other inter-molecular inter-actions, including weak C-H?O hydrogen bonds, ?-? [shortest centroid-centroid distance = 3.336?(7)?Å] and C-O?? [O?centroid distance = 3.562?(10)?Å] inter-actions, connect the various components.

Triimidazolium tris-(pyridine-2,6-di-carboxyl-ato)dysprosate(III) trihydrate.

Project description:The structure of the title compound, (C(3)N(2)H(5))(3)[Dy(C(7)H(3)NO(4))(3)]·3H(2)O, contains a mononuclear Dy(III) complex with the rare earth metal cation in a distorted tricapped trigonal-prismatic environment. The Dy(III) ion is in each case O,N,O'-chelated by three tridentate pyridine-2,6-dicarboxyl-ate anions. Three protonated imidazole mol-ecules act as counter-cations and three lattice water mol-ecules are also present. Numerous N-H?O and O-H?O hydrogen bonding inter-actions, some of which are bifurcated, help to stabilize the packing of the structure.
