X-ray crystal structure analyses of K2H[N(CH2COO)3] · H2O (I), K2H[N(CH2COO)3] · 2 H2O (II), and Cs2H[N(CH2COO)3] · H2O (III) has been done. Thermal expansion, elastic and thermoelastic properties of the title compounds have been measured employing mechanical and optical dilatometers and ultrasonic resonance techniques, respectively. They possess quite different structural motifs contrary to most other salts having a common anion. An anomalous large molecular volume and a small mean elastic stiffness of K2H[N(CH2COO)3] · 2 H2O is qualitatively interpreted by the small number of Coulomb interactions between the single charged cations and oxygen atoms of the anions. Differences in thermal and elastic properties of corresponding alkali nitrilotriacetates and alkali salts of other large anions are discussed. © 2004 Oldenbourg Wissenschaftsverlag GmbH Crystallography nationallicence Inorganic chemistry nationallicence Organic chemistry nationallicence Haussühl Eiken aut Haussühl Siegfried aut Tillmanns Ekkehart aut Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/10(2004-10-01), 644-651 2194-4946 219:10<644 2004 219 zkri https://doi.org/10.1524/zkri.219.10.644.50819 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zkri.219.10.644.50819 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Haussühl Eiken aut NATIONALLICENCE 700 1- Haussühl Siegfried aut NATIONALLICENCE 700 1- Tillmanns Ekkehart aut NATIONALLICENCE 773 0- Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/10(2004-10-01), 644-651 2194-4946 219:10<644 2004 219 zkri CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
