A Platinum(II) Diamino-β-cyclodextrin Complex:  A Crystallographic and Solution Study. Synthesis and Structural Characterization of a Platinum(II) Complex of 6A,6B-Diamino-6A,6B-dideoxycyclomaltoheptaose

The new platinum(II) complex of 6A,6B-diamino-6A,6B-dideoxycyclomaltoheptaose was synthesized and characterized by spectroscopy (NMR, FAB MS, UV, c.d.) and X-ray diffraction analysis. The complex crystallizes in the ortorhombic space group P212121 with a = 26.970(2), b = 15.102(2), and c = 16.142(2)...

description The new platinum(II) complex of 6A,6B-diamino-6A,6B-dideoxycyclomaltoheptaose was synthesized and characterized by spectroscopy (NMR, FAB MS, UV, c.d.) and X-ray diffraction analysis. The complex crystallizes in the ortorhombic space group P212121 with a = 26.970(2), b = 15.102(2), and c = 16.142(2) Å. The Pt(II) has a square-planar coordination with two chlorine atoms and two amino groups in a cis disposition. The complexation with the Pt(II) induces a distortion of the cavity. The hydrogen bonds on the secondary hydroxyl groups, which involve the functionalized rings, are longer and consequently weaker than the other hydrogen bonds.
