摘要

The crystal structure of metolazone has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional techniques. Metolazone crystallizes in space group P-1 (#2) with a = 8.1976(5), b = 14.4615(69), c = 16.0993(86) angstrom, alpha = 115.009(18), beta= 90.096(7), gamma= 106.264(4)degrees, V= 1644.52(9) angstrom(3), and Z= 4. The broad (02-1) peak at 3.42 degrees 2 theta indicates stacking faults along this direction. The crystal structure consists of alternating polar and hydrocarbon layers parallel to the ac-plane. Only one of the sulfonamide groups acts as a hydrogen bond donor. Both ring nitrogen atoms act as hydrogen bond donors, but one forms an N-H center dot center dot center dot N hydrogen bond, while the other participates in an N-H center dot center dot center dot O bond. The powder pattern has been submitted to ICDD (R) for inclusion in the Powder Diffraction File (TM), to replace entry 00-066-1624. (C)2019 International Centre for Diffraction Data.
