Organic-inorganic complex magnets ((RNH_3)_2MX_4) were synthesized, where R is a simple alkylammonium molecule (CH_3(CH_2)_<17>), a l-methyl-naphthalene (C_<10>H_9CH_2), a l-propyl-naphthalene (C_<10>H_9O(CH_2)_3), or a l-butyl-naphthalene (C_<10>H_9O(CH_2)_4), M is a 3d transition metal element, and X is a halide element(Cl). Their complexes had a layered perovskite structure checked by XRD. The distance of interlayer space between MCl-based layers was shorter for the complexes with l-butyl-naphthalene than for those with l-propyl-naphthalene. When R was a simple alkylammonium molecule, a l-methyl-naphthalene and a l-propyl-naphthalene, its Cu complexes showed ferromagnetism and its Mn complexes antiferromagnetism. However, Cu and Mn complexes with a l-butyl-naphthalene did not show ferromagnetism and antiferromagnetism, respectively. The absorption spectra of Cu complexes were also measured. When R was a simple alkylammonium molecule, a l-methyl-naphthalene, and a l-propyl-naphthalene, Cu complexes showed a D_<4h> structure for inorganic layers, while the structure for the complex with a l-butyl-naphthalene was D_<2d>.
