“…Within a project on the determination of electron density in building blocks 7 of metal organic frameworks 8 , in particular metal bio-organic frameworks (M-Bio-F), 9 we are studying hydrogen bonded networks formed by amino acids in co-crystals or salts, precursors of the MBio-F's. During this research we came across an interesting species: L-histidinium hydrogen oxalate (1), first characterized at ambient conditions by Prabu et al 10 1 has attracted our attention because of its molecular and supramolecular arrangement.…”

The accurate electron density and the linear optical properties of L-histidinium hydrogen oxalate are discussed in this paper. Two high resolution single crystal X-ray diffraction experiments were performed and compared with density functional calculations in the solid state as well as in the gas phase. The crystal packing and the hydrogen bond network are accurately investigated using topological analysis based on Quantum Theory of Atoms in Molecules, Hirshfeld surface analysis and electrostatic potential mapping. This compound also offers the possibility to test the electron density building block approach for material science and different refinement schemes for accurate positions and displacement parameters of hydrogen atoms, in the absence of neutron diffraction data.

“…Termin MOF został wprowadzony w 1995 r. w pracy Yaghiego i et al, w której opisano nowy dwuwymiarowy materiał o strukturze "siatki" i trwałych mikroporach o nazwie MOF-2 [Zn(BDC)(DMF)(H 2 O)] (BDC -kwas tereftalowy; DMF -N,N-dimetyloformamid) [5,6]. Otrzymany kilka lat później MOF-5 [Zn 4 O-(BDC) 3 ] miał już trójwymiarową strukturę, znaczną powierzchnię właściwą (2900 m [7].…”

A -koncepcja i projekt badania; B -gromadzenie i/lub zestawianie danych; C -analiza i interpretacja danych; D -napisanie artykułu; E -krytyczne zrecenzowanie artykułu; F -zatwierdzenie ostatecznej wersji artykułu StreszczenieSieci metaloorganiczne typu MOF są nową grupą materiałów mezoporowatych o hybrydowej budowie organiczno-nieorganicznej. Ich wyjątkowe cechy: dowolność doboru elementów składowych umożliwiająca uzyskanie biozgodnych struktur oraz dobrze rozwinięta powierzchnia właściwa sprawiają, że MOF-y są obiecującymi nośnikami substancji leczniczych. MOF-y mogą być wykorzystane również w tzw. terapii celowanej, dzięki dołączonym do powierzchni nośnika ligandom lub przeciwciałom. Poprzez wbudowanie w strukturę kationów o właściwościach paramagnetycznych będzie możliwe użycie ich jako kontrastu w tomografii magnetyczno-rezonansowej (MRI). Połączenie zdolności przenoszenia cząsteczek substancji leczniczych i obrazowania w jednym nośniku wskazuje na potencjalne zastosowanie MOF-ów jako teranostyków i może dawać możliwość monitorowania substancji leczniczej w czasie rzeczywistym po wprowadzeniu do organizmu. Celem niniejszej pracy jest charakterystyka nowej grupy związków i prezentacja potencjalnych możliwości ich zastosowania jako substancji pomocniczych w technologii postaci leku (Polim. Med. 2015, 45, 2, 81-93).Słowa kluczowe: polimery koordynacyjne, układy mezoporowate, teranostyki, sieci metaloorganiczne. AbstractMetal-organic frameworks (MOFs) belong to the new class of mesoporous, hybrid materials composed of metal ions and organic binding ligands. Their unique features: wide range of chemical building components, which enables obtaining biocompatible materials, and high surface area and loading capacity, make them promising drug delivery vehicles for therapeutic agents. The ability to tune their structures and porosities provides better adjustment for adsorbed drug molecule. Moreover, MOFs functionalized with ligands or antibodies can be used in cancer targeted therapy. Through the incorporation of paramagnetic metal ions into the structure, MOFs are suited to serve as magnetic resonance imaging (MRI) contrast agents. Combining drug delivery ability with imaging properties of MOFs indicates their potential use as theranostic agents and makes possible monitoring drug delivery within the body after administration in the real time. The aim of the present study is to characterize a new class of compounds and to present potential possibilities of their use as excipients in pharmaceutical technology (Polim. Med. 2015, 45, 2, 81-93).Key words: mesoporous materials, coordination polymers, theranostics, metal-organic frameworks. Sieci metaloorganiczne (MOF -metal organic frameworks) to zupełnie nowa grupa materiałów porowatych, która pojawiła się pod koniec lat 90. XX w. Są to związki o budowie hybrydowej organiczno-nieorganicznej, określane również jako porowate sieciowe polimery koordynacyjne PCP (porous coordination polymers). Strukturę MOF stanowi sieć składająca się z dwóch głównych elementów: kationów lub...

Single crystals of [Cd(terephthalate)(H 2 O) 3 ].4H 2 O (1), triaquo(1,4-benzenecarboxylato-O)cadmium tetrahydrate, are grown in a silica gel column. Crystal structure analysis shows that (1) is a polymer with metal-organic chains stacked along the a axis forming layers parallel to the ab plane. These layers are linked by an unusual hydrogen-bonded network formed by the water molecules (both`free' and coordinated ones) and the carboxylate O atoms. This network comprises tridymite-like O 8 cages which`propagate' in the direction of the a axis, mimicking the way they`propagate' along the c axis in hexagonal ice.
