摘要：

A second polymorph of the title compound [ systematic name: 1-(9H-carbazol-4-yloxy)-3-[2-(2-methoxyphenoxy)ethylamino]propan-2-ol], C24H26N2O4, is described. The other polymorph [ Chen, Zeng, Yu & Xu ( 1998). Jiegou Huaxue ( Chin. J. Struct. Chem.), 17, 325-328] also crystallizes in the space group P2(1)/c, but differs in two torsion angles of the chain connecting the aromatic residues. On the other hand, the hydrogen-bond patterns of the two polymorphs are rather similar.
