The magnetic susceptibility is measured for two series of linear organic‐inorganic coordination polymers I‐Ln and II‐Ln (Ln = La–Tb). The structure of the polymers (isostructural in each series I‐Ln and II‐Ln) differs in the length and structure of the bridges and in the nearest environment of the lanthanides. The effective magnetic moments of lanthanide atoms are determined from the magnetic susceptibility. The measured magnetic moments agree with the values characteristic of isolated trivalent 3+ ions for all cases, except for Tb which demonstrates a higher value of 12.25 μB in one of the complexes. An analysis of the X‐ray photoelectron spectrum of Tb 5s makes it possible to estimate the spin magnetic moment of the Tb ion.
