NMR of Cl" nuclei (within layer) of (C,H.,..NH.).CuCI. is observed atthe ncagnetically ordered state. Through the angular dependence of the NMRfreqt?ency, the crystallographic structure of the Crawl. layer is determined, which isslightly different from the known crystal structure at room tentperature. The ex-istence of variotms mnoment directions is shown in (C3H 7 NH.).CuCl.. The mag-netjc coupling between layers is discussed. The observed magnetization of(C,H2..lNH.)2CUCl4 (w=l, 3 and 4) is compared with the renorxnalized spinwave theory. It is also shown that the magnetization follows the "T"'-law" givenas,<S>/S= l -a(T/T.)"", with a--0.45. The field dependent behavior of the ntag-netization of (C2H,NH.).CUCI. is discussed at antiferromagnetic state.
