Abstract
<jats:title>Abstract</jats:title> <jats:p>We succeeded in synthesizing a novel cuprate compound, [Cu2(CO3)2(bpp)2.5]·5.5H2O (1) (bpp: 1,3-bis(4-pyridyl)propane). Its structural determination reveals that 1 has a ladder-like configuration formed by the alternate stacking of two Cu2+ ions and a CO32− ion, each of which is linked by a bpp molecule. The results of magnetic susceptibility measurements indicate that the obtained magnetic susceptibility curve can be reproduced faithfully by a magnetically isolated spin ladder-based model with the ladder-rung magnetic interaction, Jrung/kB = 366 K and the ladder-leg interaction, Jleg/kB = 11.5 K, where J is defined as being positive (negative) for antiferromagnetic (ferromagnetic) interactions.</jats:p>
