Hydrothermal Synthesis and Crystal Structure of a Manganese(II) Complex: Mn1.5(cbba)3(phen)

A new metal-organic complex Mn-1.5(cbba)(3)(phen) (Hcbba = 2-(4'-chlorine-benzoyl)benzoic acid, phen = 1,10-phenanthroline) 1 has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analyses, TG and IR spectroscopy. The compound crystallizes in triclinic, space group P $(1) over bar $ with a = 12.137(2), b = 14.535(3), c = 14.894(3) angstrom, alpha = 86.380(3), beta = 70.381(3), gamma = 72.647(3)degrees, V = 2360.3(8) angstrom(3), C107H64Cl6Mn3N4O18, M-r = 2071.14, D-c = 1.457 g/cm(3), mu(MoK alpha) = 0.638 mm(-1), F(000) = 1055, Z = 1, the final R = 0.0638 and wR = 0.1905 for 6155 observed reflections (I > 2 sigma(I)). It exhibits a 3D supramolecular network through hydrogen bonding and pi-pi stacking interactions.
