This study examines the lanthanide calcium oxyborates Ca4LnO(BO3)3 (Ln = La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Y, Er, Yb). The reported monoclinic structure (space group Cm) was confirmed using powder X-ray diffraction. The magnetic Ln3+ ions are situated in well-separated chains parallel to the c axis in a quasi-one-dimensional array. Here we report the first bulk magnetic characterization of

CAPE CHEMISTRY: 2020
Calcium is a stronger reductant than sodium according to E o (standard electrode potential) values, but the metal reactivity series suggests that calcium is less reactive than sodium. This discrepancy arises because calcium reacts at a much slower rate , in displacement reactions for example, which in turn happens because two electrons must be removed, not one as for sodium.
