摘要：

The sublimation of 2-amino-4,6-dichloro-1,3,5-triazine yielded well developed needle-shaped crystals whose X-ray-powder pattern did not match with that of the known orthorhombic compound with the space group P2(1)2(1)2(1) [1]. The investigation of a needle-shaped single crystal revealed a new monoclinic modification, which crystallizes in the space group P2(1)/c. At T = 220 K the following lattice parameters were refined: a 8.403(l) angstrom, b = 12.152(1) angstrom, c = 13.898(2) angstrom and beta 123.01(1)degrees. The unit cell volume amounts to 1190.1(3) angstrom(3) for 8 formula units.
