Tetra-kis(2-amino-4-methyl-pyridinium) cyclo-tetra-?(2)-oxido-tetra-kis-[dioxido-vanadate(V)] tetra-hydrate.

ABSTRACT: The asymmetric unit of the title compound, (C(6)H(9)N(2))(4)[V(4)O(12)]·4H(2)O, contains half of a [V(4)O(12)](4-) anion, two 2-amino-4-methyl-pyridinium, (2a4mpH)(+), cations and two water mol-ecules. One water mol-ecule is disordered over two sets of sites with equal occupancies and the H atoms for this mol-ecule were not included in the refinement. The cation lies on an inversion center with four tetra-hedral VO(4) units each sharing two vertices, forming an eight-membered ring. In the crystal, the components are linked by inter-molecular N-H?O hydrogen bonds, forming a one-dimensional network along [100]. Further stabilization is provided by weak inter-molecular C-H?O hydrogen bonds. In addition, ?-? stacking inter-actions with centroid-centroid distances of 3.5420?(18), 3.7577?(18) and 3.6311?(19)?Å are observed.

5,10,15,20-Tetra-kis(1-methyl-pyridinium-4-yl)porphyrin tetra-iodide tetra-hydrate.

Project description:The asymmetric unit of the title compound, C(44)H(38)N(8) (2+)·4I(-)·4H(2)O, comprises two halves of non-equivalent cations of 5,10,15,20-tetra-kis-(1-methyl-pyridinium)porphyrin (with the full mol-ecule of each completed by the application of inversion symmetry), four charge balancing iodide anions and four water mol-ecules of crystallization (two water mol-ecules are fully occupied and four mol-ecules have a site occupancy of 50%). The porphyrin cations are arranged into supramolecular columns parallel to the b axis, mediated by π-π [centroid-centroid distance = 3.762 (4) Å] and C-H⋯π supra-molecular inter-actions [C⋯centroid distance = 3.522 (7) Å, C-H⋯centroid = 128°], leading to the formation of columns parallel to the b axis. The close packing leads to the presence of a one-dimensional channel filled with partially occupied water mol-ecules engaged in O-H⋯O and O-H⋯I hydrogen bonds.

Bis(2-amino-4-methyl-pyridinium) terephthalate tetra-hydrate.

Project description:In the crystal structure of the title salt, 2C(6)H(9)N(2) (+)·C(8)H(4)O(4) (2-)·4H(2)O, the terephthalate carboxyl-ate groups inter-acts with the 2-amino-4-methyl-pyridinium cations via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. The water mol-ecules form an R(6) (6)(12) ring motif through O-H?O hydrogen bonds and these motifs are fused, forming a supra-molecular chain along the c axis. The R(2) (2)(8) and R(6) (6)(12) ring motifs are connected via O-H?O hydrogen bonds. In addition, ?-? stacking inter-actions are observed between the pyridinium rings [centroid-centroid distance = 3.522?(12)?Å].

Tetra-?-oxido-tetra-kis{dioxido[3-(2-pyrid-yl)-1H-pyrazole]molybdenum(VI)}.

Project description:In the title compound, [Mo(4)O(12)(C(8)H(7)N(3))(4)], the Mo(VI) ion has a distorted octa-hedral coordination completed by two terminal O atoms, two ?-oxide atoms and two N atoms from one 3-(2-pyrid-yl)-1H-pyrazole ligand. It is noteworthy that in the tetranuclear unit ( symmetry), any three Mo(VI) atoms define a plane, and the fourth lies 1.8?(1)?Å out of that plane. The degree of linearity of the oxide bridges between two Mo atoms is 175.38?(13)°. Moreover, the N-H group forms an intra-molecular hydrogen bond (four per mol-ecule).

Project description:In the crystal structure of the title compound, 4C5H6ClN2 (+)·H2P6O18 (4-), the [H2P6O18](4-) anions are interconnected by O-H⋯O hydrogen bonds, leading to the formation of infinite ribbons extending along the a-axis direction. These ribbons are linked to the organic cations, via N-H⋯O and C-H⋯O hydrogen bonds, into a three-dimensional network. The six P atoms of the [H2P6O18](4-) anion form a chair conformation. The complete cyclohexaphosphate anion is generated by inversion symmetry.

cyclo-Tetra-kis{?-N'-[(8-oxidoquinolin-7-yl)methyl-idene]isonicotino-hydrazidato}tetra-zinc tetra-hydrate.

Project description:In the title compound, [Zn(4)(C(16)H(10)N(4)O(2))(4)]·4H(2)O, the N'-[(8-oxidoquinolin-7-yl)methyl-idene]isonicotinohydrazidate (L(2-)) ligand binds to the metal ions, forming stable five- and six-membered chelate rings, leaving the pyridyl groups free. The compound is a tetra-nuclear Zn(II) complex centered about a fourfold roto-inversion axis, with the ligand coordinating in the doubly deprotonated form. The Zn(II) atom has a distorted square-pyramidal geometry being coordinated by one N and two O-atom donors from the doubly deprotonated L(2-) ligand, and by one N atom and one O-atom donor from a symmetry-related L(2-) ligand. In the crystal, four symmetry-related lattice water mol-ecules, centred about a fourfold roto-inversion axis, form a cyclic tetra-mer through O-H?O hydrogen bonds. These tetra-mers connect to the complex mol-ecules through O-H?N hydrogen bonds, forming a chain propagating along [100]. Neighbouring mol-ecules are linked by ?-? inter-actions [centroid-centroid distance = 3.660?(2)?Å] involving the quinolidine rings.

Project description:In the title compound, {[NiWO(4)(C(16)H(36)N(4))]·4H(2)O}(n), the Ni(II) ion lies on an inversion center and is octahedrally coordinated by four N atoms of the tetradentate macrocyclic 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-decane (L) ligand in the equatorial plane and two O atoms of [WO(4)](2-) anions in axial positions. Each [WO(4)](2-) anion bridges two adjacent [NiL](2+) cations, forming a chain along [001]. The chains are further connected via N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions, generating a three-dimensional structure.

Bis{[amino-(iminium-yl)meth-yl]urea} tetra-kis-{2-[(di-methyl-amino)(iminium-yl)meth-yl]guanidine} di-μ6-oxido-tetra-μ3-oxido-tetra-deca-μ2-oxido-octa-oxidodeca-vanadium(V) tetra-hydrate.

Project description:The title compound, (C4H12N5)4(C2H7N4O)2[V10O28]·4H2O, is a by-product obtained by reacting ammonium metavanadate(V), metformin hydro-chloride and acetic acid in the presence of sodium hypochlorite, at pH = 5. The crystal structure comprises a deca-vanadate(V) anion (V10O28)6- lying on an inversion centre in space group P , while cations and solvent water mol-ecules are placed in general positions, surrounding the anion, and forming numerous N-H⋯O and O-H⋯O hydrogen bonds. Metforminium (C4H12N5)+ and guanylurea (C2H7N4O)+ cations display the expected shape. Inter-estingly, in physiology the latter cation is known to be the main metabolite of the former one. The reported structure thus supports the role of sodium hypochlorite as an oxidizing reagent being able to degrade metformin hydro-chloride to form guanylurea.

Project description:In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds into chains along [100]. These chains are further linked by weak ?-? inter-actions with centroid-centroid distances in the range of 3.609?(2)-3.758?(1)?Å, forming a three-dimensional supra-molecular network.

Project description:The title compound, [Cu(4)(C(7)H(6)N(2)O(3))(4)(H(2)O)(4)]·14H(2)O, a tetra-nuclear [2 × 2] grid-type complex with S4 symmetry, contains four Cu(II) atoms which are bridged by four pyrazole-carboxyl-ate ligand anions and are additionally bonded to a water molecule. Each Cu(II) atom is coordinated by two O atoms of the carboxyl-ate and acetyl groups, two pyrazole N atoms of doubly deprotonated 3-acetyl-4-methyl-1H-pyrazole-5-carb-oxy-lic acid and one O atom of a water mol-ecule. The geometry at each Cu(II) atom is distorted square-pyramidal, with the two N and two O atoms in the equatorial plane and O atoms in the axial positions. O-H⋯O hydrogen-bonding interactions additionally stabilize the structure. One of the uncoordinated water molecules shows half-occupancy.

Project description:The crystal structures of the title salts, (C7H11N2)2[Mn(NCS)4] (1) and (C7H11N2)3[Mn(NCS)5] (2), consist of manganese(II) cations that are tetra-hedrally (1) or trigonal-bipyramidally (2) coordinated to four or five terminal N-bonded thio-cyanate ligands, respectively, into discrete anionic complexes. The negative charge is compensated by two (1) or three (2) 4-(di-methyl-amino)-pyridinium cations, which are protonated at the pyridine N atom. The asymmetric unit of compound 1 consists of one anionic complex and two 4-(di-methyl-amino)-pyridinium cations, whereas that of compound 2 consists of two anionic complexes and six 4-(di-methyl-amino)-pyridinium cations, all of them located in general positions. These complexes are linked by N-H⋯S, C-H⋯S and C-H⋯N hydrogen-bonding inter-actions between the 4-(di-methyl-amino)-pyridinium cations and the thio-cyanate ligands into three-dimensional network structures.
