TL;DR: In this paper, four new metal-organic frameworks (MOFs), namely, [Zn2L]n (1), [Mn(H2L)(H2O)]n (2), [Cd(H 2L)2]n·nH 2O (3) and [Pb2L(h2O)n·3nH2 O·nDMF (4), have been prepared by using a tetracarboxylic acid ligand H4L (H4L = 5-(bis(4-
Abstract: Four new metal–organic frameworks (MOFs), namely, [Zn2L]n (1), [Mn(H2L)(H2O)]n (2), [Cd(H2L)(H2O)2]n·nH2O (3) and [Pb2L(H2O)]n·3nH2O·nDMF (4), have been prepared by using a tetracarboxylic acid ligand H4L (H4L = 5-(bis(4-carboxybenzyl)amino)isophthalic acid) under hydrothermal conditions and structurally characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction analysis and powder X-ray diffraction. Structural analyses revealed that 1, 2 and 4 exhibit three-dimensional network structures. The structure of 1 can be symbolized as a 2-nodal 6-connected net with a (411·64)(47·68) topology. The framework of 2 can be considered as a 4-connected net with a (62·84)(63·83) topology. The structure of 4 can be regarded as a 5-connected net with a 43·66·8 topology. In contrast, 3 exhibits a 2D structure with a 3,3-connencted (63)2 topology. These MOFs exhibit excellent photocatalytic activities for dye degradation under visible light irradiation. Furthermore, 2 displays weak antiferromagnetic interaction at low temperature.

Abstract: Inorganic molecules (ions) and ligands are classified into diatomic, triatomic, four-atomic, five-atomic, six-atomic, and seven-atomic types, and their normal modes of vibration are illustrated and the corresponding vibrational frequencies are listed for each type. Molecules of other types are grouped into compounds of boron, carbon, silicon, nitrogen, phosphorus, and sulfur, and the structures and infrared (IR)/Raman spectra of select examples are shown for each group. Group frequency charts including band assignments are shown for phosphorus and sulfur compounds. Other group frequency charts include hydrogen stretching frequencies, halogen stretching frequencies, oxygen stretching and bending frequencies, inorganic ions, and metal complexes containing simple coordinating ligands.

TL;DR: Rational design and synthesis of polynuclear lanthanide–hydroxo species via ligand-controlled hydrolysis of the lanthanides ions yielded a series of highly sophisticated yet structurally well-defined lanthanid–hydrogen complexes that are potentially applicable to the study of biomimetic catalysis of phosphate diester cleavage.
