The X-ray crystal structure of a 1:1 adduct between α-cyclodextrin and cyclobutane-1,1-dicarboxylatodiammineplationum(II)

Abstract

In the second sphere co-ordination of a cyclobitane-1,1-dicaroxy;atiammimeplatinum(II)µ-cyclodextrin, stabilisation of the crystalline adduct is achieved by the cyclobutane ring if the guest penetrating into the cavity of the hoist and the ammine ligands on the guest participating in the formation of two(N–H ··O) hydrogen bonds with secondary hydroxy group at C(3) on neighboring α-D-glucopyranosidic units in the host.
