摘要

As a part of studies on MDR reversal agents, structure of the 9,10-dihydro-11, 12-bis [(1, 3,3 -trimcthylurcido)methyl]-9,10-ethanoanthracene dihydrate is reported. Crystal data: C26H34N4O2 x 2 H2O; mol. mass 470.60; monoclinic; space group: C2/c, a = 15.7492(6) angstrom; b = 7.2245(3) angstrom; c = 24.3442(10) angstrom; beta = 106.795(2)degrees; V = 2651.73(22) angstrom(3); z = 4; dx = 1.179 mg/m(3); mu = 0.64 mm(-1); F(000) = 1016; final R = 0.061 for 2501 reflections [I > 4 sigma (I)]. Only half of the molecule is unique. The two nonplanar rings from the independent part of 9,10-dihydro-9,10-ethanoanthracene adopt a boat conformation. Crystallographic data demonstrate the "syn-syn" conformation of urea substituents in the molecule. In the crystal, water molecules are linked to the main species by H-bonds: O3'center dot center dot center dot H12w-O1-H11w center dot center dot center dot O3'(1.5 - x, 0.5 - y, 1 - z).
