Article abstract of DOI:10.1246/bcsj.64.149

The crystal and the molecular structures of the title complex were determined by means of the single-crystal X-ray diffraction method.The crystal of PtC28H23O5N2Cl4, F.W. 804.40, (black-violet in color) is monoclinic, with the space group of P2₁/a, a=18.293(4), b=9.682(2), c=15.797(3) Angstroem, β=96.55(2) deg, U=2779.6(9) Angstroem³, Z=4, D_m=1.90, D_x=1.92 g*cm^(-3), and μ (MoKα)=57.37 cm^(-1).The platinum atom is in a hexa-coordinated octahedral geometry, where one 2-(2-benzoxazolyl)phenolate(bxp-) ion is chelated with its N and phenolato O atoms.The bxp- ligand as well as the free Hbxp molecule are both approximately planar, and their planes are approximately in parallel: They are arranged alternately and are laid roughly along the a-axis.Although the overlapping areas of the neighboring rings are only 23 and 13percent respectively of the whole ring area, the interplane distances are 3.42 and 3.49 Angstroem.
