FLOSS (fluorescence labeling of surface species) enables one to identify and quantify very low concentrations of surface functional groups. Unlike most surface analytical techniques, FLOSS can provide absolute, as well as relative, surface coverage determination. However, as with any other surface derivatization technique, FLOSS provides a lower limit to surface coverage. The specificity of FLO...

In the title compound, [Li(2)(C(6)H(3)N(2)O(4))(2)(H(2)O)(3)](n), the coordination number for both independent Li(+) cations is five. One of the Li(+) ions has a distorted trigonal-bipyramidal geometry, coordinated by one of the carboxyl O atoms of a 3-carboxy-pyrazine-2-carboxyl-ate ligand, two O atoms from two water mol-ecules, and an N and a carboxyl-ate O atom of a second 3-carboxy-pyrazine...

In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis anions associate through head-to-tail carb-oxy-lic acid-carboxyl O-H⋯O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter-linked through the carboxyl groups, forming cyclic R(2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine-carboxyl...

In the title polymer, [Mn(C(8)H(8)O(5))(H(2)O)(2)](n), the Mn(II) atom is in a distorted octa-hedral coordination mode, binding to the bridging O atom of the bicyclo-heptane unit, two O atoms from corresponding carboxyl-ate groups, one carboxyl-ate O atom from a symmetry-related bridging ligand and two water O atoms. This arrangement leads to the formation of polymeric chains propagating parall...

In the title compound, [Mn(NCS)2(C15H14N2O4)(H2O)3]·2H2O, the metal ion is octa-hedrally coordinated by three water mol-ecules, one carboxyl-ate O atom from a 1,1'-(propane-1,3-di-yl)bis-(pyridinium-4-carboxyl-ate) ligand and two N atoms from two thio-cyanate anions in cis positions, forming a mononuclear complex mol-ecule. In the crystal, mol-ecules are connected into a three-dimensional archi...

The title compound, C(10)H(6)O(8)·2C(3)H(7)NO(2), crystallizes as an adduct with the acid and amino acid mol-ecules in their neutral forms. The asymmetric unit contains one half of a centrosymmetric pyromellitic acid mol-ecule and one sarcosine mol-ecule. The sarcosine has the amine group protonated and the carboxyl group deprotonated, as is usual for amino acids (zwitterionic form). The pyrome...

In the title compound, [CdCu(2)(C(12)H(11)N(2)O(5))(2)(H(2)O)(3)]·2H(2)O, the Cu(II) atoms are in a square plane of N(2)O(2) atoms contributed by the tetra-dentate Schiff base trianion. The Cu(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Cd(II) atom is connected via the carboxyl-ate groups, forming a heterotrinuclear Cu(I...

In the title polymeric compound, [Cd(C(8)H(3)NO(6))(C(10)H(8)N(2))](n), two O atoms from both carboxyl-ate groups of a nitro-phthalate anion coordinate to the Cd(II) cation, forming a seven-membered chelate ring and two carboxyl-ate O atoms from another two nitro-phthalate anions and a 2,2'-bipyridine ligand coordinate to the Cd cation to complete the distorted octa-hedral coordination geometry...

The tiltle complex, [La(2)(C(7)H(7)NO(2))(4)Cl(2)(H(2)O)(6)]Cl(4)·2H(2)O, is a centrosymmetric dimer formed by edge-sharing LaO(5)(H(2)O)(3)Cl polyhedra linked together by a carboxyl-ate ligand. The two La(III) metal ions are linked by two bidentate bridging carboxyl-ate groups with a κ(2)O:O' coordination mode and two bidentate chelating bridging carboxyl-ate groups with a κ(3)O:O,O' coordinat...

In the centrosymmetric polymeric title compound, {[CoHo(2)(C(14)H(8)N(2)O(5))(4)(H(2)O)(4)]·4H(2)O}(n), the Ho(III) ion is coordinated by one water mol-ecule and four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands in a distorted square-anti-prismatic arrangement. The Co(II) ion, located on an inversion center, is coordinated by two pyridine N atoms, two carboxyl-ate O atoms and two water m...
