Organic-inorganic complex magnets ((RNH3)2MX4) were synthesized, where R is a simple alkylammonium molecule (CH3(CH2)17), a 1-methy1-naphthalene (C10H9CH2), a 1-pro-pyl-naphthalene (C10H9O(CH2)3), or a 1-buty1-naphthalene (C10H9O(CH2)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 1-buty1-naphthalene than for those with 1-propy1-naphthalene. When R was a simple alkylammonium molecule, a 1-methy1-naphthalene and a 1-propy1-naphthalene, its Cu complexes showed ferromagnetism and its Mn complexes antiferromagnetism. How-ever, Cu and Mn complexes with a 1-buty1-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 1-methy1-naphthalene, and a 1-propy1-naphthalene, Cu complexes showed a D4th structure for inorganic layers, while the structure for the complex with a 1-buty1-naphthalene was D2d.
