A simple method was suggested for preparing N-carboxyethyl-tris(hydroxymethyl)aminomethane (homotricin) (II). On the basis of compound II, the 1:1 Cu complex, [Cu(OCH2C(CH2OH)2NHCH2CH2COO)]4·nH2O (n = 4–11.25) (III), which is alkoxycarboxylate, was synthesized. The crystal structure of III was found to correspond to a cubane-like tetranuclear cluster (an automated Bruker X8Apex diffractometer with CCD detector (MoK radiation, graphite monochromator, v = 1.11°-27.5°), 8016 reflections, space group P , a = 12.5573(3), b = 19.1012(4), c = 21.2903(5) A, a = 80.7770(10)°, beta = 75.7430(10)°, y = 75.2260(10)°, V = 4761.62(19) A3, p(calcd.) = 1.704 g/cm3, Z = 4). The crystals are unstable due to the large number of water molecules Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Pestov, A. V.; Virovets, A. V.; Podberezskaya, N.
