Abstract
The new platinum(II) complex of 6A, 6B-diamino-6A, 6B-dideoxycyclomalt oheptaose 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 P2(1)2(1)2(1) with a = 26.970(2), b = 15.102(2), and c = 16.142(2) Angstrom. The Pt(II) has a square-planar coordination with two chlorine atoms and two amino groups in a cis dis position. The complexation with the Pt(II) induces a distortion of the cavity. The hydrogen bonds on the secondary hydroxyl groups, which in volve the functionalized rings, are longer and consequently weaker tha n the other hydrogen bonds.
