1D Heterometallic Oxalate Compounds as Precursors for Mixed Ca–Cr Oxides – Synthesis, Structures, and Magnetic Studies

“…A similar phenomenon was observed during the thermal decomposition of the heterometallic compound {Ba 6 (H 2 O) 17 [Cr(C 2 O 4 ) 3 ] 4 }·7H 2 O. [15] The mass of a green residue, which corresponds to a mixture of CaCrO 4 and 1/2Cr 2 O 3 (exp. 28.29 %; calcd.…”

“…Calcium chromate crystallizes as a zircon-type structure in the www.eurjic.org FULL PAPER Figure S5a). [15] . Such a composition is in accordance with the DTA curve, which shows an endo thermic maximum at 1068°C that corresponds to the formation of the β phase.…”

“…[14] The C 2 O 4 2-anion readily decomposes to the vapour phases CO 2 and CO at low temperatures; hence, oxalate-based solids could serve as a convenient source of oxides. [15] Heterometallic oxalate complexes have already been used for the preparation of mixed-metal oxides. [15][16][17][18][19][20][21][22][23] In our recently published articles, we reported the use of the new compound {Ba 2 O 9 through thermal decomposition at a specific temperature.…”

Synthesis, Crystal Structure and Thermal Behavior of a 3-D Barium(II)/Iron(III)-Oxalate Polymer

“…This compound has proven to be a useful precursor for the synthesis of highly versatile complex salts with the unprecedented potential of accumulating within a single system a whole set of relevant functionalities, such as nanoscale structural features, extended hydrogen bonding, magnetic interactions [13]- [15]. Moreover, it has received great attention in the field of materials science among other reasons for its use as a convenient route for the preparation of technologically important metallic composite oxides [16].…”
