A Covalent Organic Framework with 4 nm open pores.

The synthesis and characterization of a new mesoporous Covalent Organic Framework BTP-COF is described, the latter having fully accessible pores with an open diameter of 4.0 nm.

Reinvestigation of the M(II) (M = Ni, Co)/tetrathiafulvalenetetracarboxylate system using high-throughput methods: isolation of a molecular complex and its single-crystal-to-single-crystal transformation to a two-dimensional coordination polymer.

A high-throughput methodology combined with X-ray powder diffraction measurements was used to investigate the reactivity of the TetraThiaFulvalene TetraCarboxylic acid ((TTF-TC)H(4)) with divalent metals (M = Ni, Co) under various reaction conditions (stoichiometry, pH, temperature). Two new crystalline phases were identified and then studied by single crystal X-ray diffraction. Whereas the first one appears to be a simple salt, the second one, formulated {[M(H(2)O)(4)](2)(TTF-TC)}·4H(2)O, is built of 2:1 M:TTF-TC molecular complexes and labeled MIL-136(Ni, Co) (MIL stands for Materials Institute Lavoisier).

The crystal structure of the title compound, {[Er(2)(C(2)H(4)O(6)PS)(OH)(3)(H(2)O)]·H(2)O}(n), consists of two Er(3+) ions, one (C(2)H(4)O(6)PS)(3-) ion, three OH(-) ions, and two water mol-ecule. The Er(3+) ions form ErO(8) polyhedra., which are connected by μ- and μ(3)-O atoms.

Poly[[diaqua-μ(2)-hydroxido-(μ(7)-2-phos-pho-nato-ethane-sulfonato)-dicopper(II)] trihydrate].

The crystal structure of the title compound, [Cu(2)(C(2)H(4)O(6)PS)(OH)(H(2)O)(2)]·3H(2)O, consists of two Cu(2+) ions, one (O(3)PC(2)H(4)SO(3))(3-) ion and one OH(-) ion, as well as five water mol-ecules, two of which are coordinated to Cu(2+). The Cu(2+) ions are coordinated by six O atoms. The CuO(6) polyhedra are connected by μ- and μ(3)-O atoms into zigzag chains along the b axis.

Systematic investigation of lanthanide phosphonatoethanesulfonate framework structures by high-throughput methods, Ln(O3P-C2H4-SO3)(H2O) (Ln=La-Dy).

Following the strategy of using polyfunctional phosphonic acids for the synthesis of new metal phosphonates, the flexible organic linker molecule 2-phosphonoethanesulfonic acid, H2O3P-C2H4-SO3H (H3L), was used in a high-throughput (HT) investigation of lanthanide phosphonatoethanesulfonates. Two HT experiments comprising 96 individual hydrothermal reactions were performed to systematically investigate the influence of pH, rare earth ion, molar ratio of Ln3+:H3L, and the counterion in the system LnX3/H3L/NaOH/H2O with X=NO3-, Cl-, and CH3COO-. Whereas under basic conditions Ln(OH)3 is formed, acidic reaction conditions lead to nine isotypic compounds Ln(O3P-C2H4-SO3)(H2O) with Ln=La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8), and Dy (9).
