TL;DR: The thermal reactivity of all compounds and the transformation behavior as well as the range of thermodynamic stability of the dimorphic modifications were studied using DTA-TG-MS and DSC measurements, temperature dependent X-ray powder investigations, and crystallization experiments.
Abstract: A second modification of the literature-known copper(I) coordination polymer CuCl(pyridazine) was prepared by the reaction of CuCl with pyridazine in acetonitrile. The crystal structure of catena[C...

TL;DR: In this article, a single-crystal X-ray diffraction was used to determine the structure of a 3-carboxyphenyl sulfonyl sulfonyl glycine (H3L1) ligand.
Abstract: One novel N-[(3-carboxyphenyl)sulfonyl]glycine (H3L1) ligand (1) was prepared in high yield, and its structure was determined by single-crystal X-ray diffraction. Reaction of H3L1 with Mn(ClO4)2·6H2O at different pH values gave two new dinuclear complexes: [Mn2(HL1)2(phen)4]·16H2O (2) and [Mn2L1(phen)4(H2O)]ClO4·3H2O (3) (phen = 1,10-phenanthroline). Additionally, two copper(II) complexes, [K2Cu(L2)2(H2O)2]n (4) and [CuL2(H2O)]2·2H2O (5), involving another novel ligand, N,N′-(1,3-phenylenedisulfonyl)bis(glycine) (H2L2), were prepared by a one-pot reaction of 1,3-phenylenebis(sulfonyl chloride), glycine, and KOH or triethylamine in the presence of CuII ions. A self-assembled (H2O)30 cluster containing a puckered (H2O)12 ring core was found in 2, which presents a new mode of association of water molecules not predicted theoretically or previously observed experimentally. Furthermore, 2 forms a 2-D supramolecular structure through hydrogen bonding and unique π–π stacking interactions. In 3, there also exist discrete trimeric water clusters. The identity of the base determines the specific structural characteristics of 4 and 5. When potassium hydroxide was used for the synthesis of 4, it led to a 3-D copper(II)–potassium(I) coordination polymer; when triethylamine was used, paddle-wheel dinuclear units of copper(II) carboxylate were produced. Magnetic measurements show that there are weak antiferromagnetic interactions in 2–4. In 5 the χMT vs. T curve shows a minimum at 110 K and a climb from 110 K to 5 K, then a long-range antiferromagnetic ordering occurs, as revealed by a decrease in χMT with T.

TL;DR: In this article, a simple room temperature solution-based method for the preparation of highly porous coordination polymer films on the internal surface is reported, and the resulting metalorganic polymer hybrid (MOPH) maintains a high specific micropore surface area of 389 m2 g•1 and thermal stability above 250 °C in air.
Abstract: A simple room temperature solution‐based method for the preparation of highly porous
iron(III) benzenetricarboxylate coordination polymer films on the internal surface
of a macroporous polystyrene‐divinylbenzene‐methacrylic acid polymer is reported
The resulting metal‐organic polymer hybrid (MOPH) maintains a high specific micropore
surface area of 389 m2 g‐1 and thermal stability above 250 °C in air The MOPH preparation is readily adapted
to a capillary column, yielding a flow‐through separation device with excellent flow
permeability and modest back‐pressure The excellent separation capability of the
MOPH column is demonstrated by enriching phosphopeptides from mixtures of digested
proteins This approach to MOPH synthesis is easily implemented and likely adaptable
to a wide range of coordination polymers and metal‐organic frameworks

TL;DR: During the syntheses of 2-4, single crystals of dppeS2 were isolated, which indicates it was substituted by tpt ligand and also confirmed the transformation of sulfur from CuSCN to dppe.
Abstract: The solvothermal reaction of CuSCN with 1,2-bis(diphenylphosphino)ethane (dppe) yielded a coordination polymer, which was characterized to be a complex of CuCN and 1,2-bis(diphenylthiophosphinyl)ethane (dppeS2): [(CuCN)2(dppeS2)]n (1). The identification of complex 1 reveals that CuSCN was decomposed and the sulfur was transferred to dppe, and represents a new example of the transformation of inorganic sulfur to organic sulfur. The weak coordination interactions between CuCN and dppeS2 indicate that dppeS2 may be substituted by ligands with strong coordination ability. The ligand 2,4,6-tris(2-pyridyl)-1,3,5-triazine (tpt) was chosen as a substitute ligand. Three novel CuCN coordination polymers of tpt were synthesized and characterized: [Cu2(CN)2(tpt)]n (2) with a 3-D (10,3)-a network, [Cu2(CN)2(tpt)]n (3) and [Cu2(SCN)(CN)(tpt)]n (4) both with a 2-D (6,3) network, and only complex 2 can be obtained from CuCN directly. Interestingly, compounds 2 and 3 are genuine high-dimensional supramolecular isomers. During the syntheses of 2–4, single crystals of dppeS2 were isolated, which indicates it was substituted by tpt ligand and also confirmed the transformation of sulfur from CuSCN to dppe. The transformation of sulfur can be observed only when the temperature is relative high (>160 °C). At 140 °C, complex 5 containing only CuSCN was attained and no dppeS2 has been monitored in the resulting filtrate.
