TL;DR: The structure of rctt-(2,4-tpcb-ht) in the form of crystalline Rctt-1,3-bis(2-pyridyl)-2, 4-bis-cyclobutane [rctt]-1.5(H2O) has been confirmed by single-crystal X-ray diffraction as discussed by the authors.

Abstract: The title dimeric complex, bis{μ-2,2′-[hexane-1,6-diylbis(nitrilomethylidyne)]diphenolato-1:2κ4O,N:N′,O′}dicopper(II),[Cu2(C20H22N2O2)2], has been investigated by single-crystal X-ray diffraction, by thermogravimetric analysis and differential scanning calorimetry, and also by FT–IR spectroscopy. Different synthetic and crystallization procedures gave crystals which were quite different in appearance, and it was initially thought that these were different polymorphic forms. Subsequent structure determination showed, in fact, serendipitous preparation of crystals in the P41 space group by one method and in space group P43 by the other. In these enantiomorphic structures, the Cu atoms have a distorted flattened tetrahedral coordination, with Cu—N and Cu—O distances in the ranges 1.954 (4)–1.983 (4) and 1.887 (4)–1.903 (4) A, respectively.

TL;DR: In this paper, the magnetic moment measurements of the new synthesized molecular magnet Mn-12-methanoate were reported, and they showed splitting between zero-field-cooled and fieldcooled magnetic moment dependence on temperature below, blocking temperature, which amounts to approximate to 3 K in weak magnetic field.
