✦ Synopsis

A

suberato-pillared Mn(II) coordination polymer Mn 2 (H 2 O)(C 8 H 12 O 4 ) 2 was hydrothermally synthesized at 1701C for 3 days and characterized by single-crystal X-ray diffraction. Crystal data: monoclinic,

, R 1 ¼ 0:064 and wR 2 ¼ 0:162: The compound shows a layered structure consisting of inorganic Mn oxygen polyhedral layers and organic regions. The inorganic Mn oxygen layers are generated from Mn 2 O 10 bioctahedral units, which share corners with neighbors to form zigzag chains along the [001] direction and are, along the [010] direction, further connected by carboxylate groups of the suberato ligands and hydrogen bonds. The magnetic studies indicated that the compound becomes antiferromagnetic at low temperatures with T N! eel ¼ 12 K and follows Curie-Weiss law v m ðT þ 22:429Þ ¼ 4:48 cm 3 mol À1 K between 25 and 300 K. Upon heating in Ar stream, Mn 2 (H 2 O)(C 8 H 12 O 4 ) 2 decomposes in three steps. # 2002 Elsevier Science (USA)
