%X The hydrothermal synthesis of the AlPO4-17, SAPO-44, MnAPSO-44 and intermediate solid phases [samples (APO)N, (APSO)N and Mn (APSO)N] in the presence of cyclohexylamine (cha) is described. (APO)N, (APSO)N and Mn (APSO)N represent unknown, layer-type, crystalline phases with different chemical compositions. These phases are predominantly formed at a high cha concentration and low crystallization temperature. All synthesized materials contain protonated cha in their structure, but only in AlPO4-17, (APO)N,(APSO)N and Mn (APSO)N is the -OH group also found. The calcination of the unknown phases leads to the loss of crystallinity and causes a complete breakdown of the crystal structure above 270&#176;C.
