New complexes of general formula (I) in which R.sub.1 and R.sub.2 together form a saturated or unsaturated polycyclic carbocyclic radical containing 7 to 12 carbon atoms, or a saturated or partially saturated mono-, bi- or tricyclic heterocyclic radical containing 5 to 11 chain members and a hetero-atom chosen from oxygen, sulphur or nitrogen, which latter atom can optionally be substituted by an alkoxycarbonyl radical, and, X.sub.1 and X.sub.2 represent chlorine atoms or together form either a radical of structure: ##STR1## in which n is 0 to 2 and R.sub.6 and R.sub.7, which are identical or different, are hydrogen atoms or, when n=1, can be alkyl radicals or form, together with the carbon atom to which they are attached, a cyclobutyl radical, or a radical of structure: ##STR2## in which n, R.sub.6 and R.sub.7 are defined as above, or their salts where such exist, and their hydrates, their preparation and the pharmaceutical compositions which contain them. ##STR3##
通用公式(I)中的新配合物,其中R.sub.1和R.sub.2共同形成含有7至12个碳原子的饱和或不饱和多环碳环基,或含有5至11个链成员和氧、硫或氮中的异原子的饱和或部分饱和的单、双或三环杂环基,后一种原子可以选择性地由烷氧羰基基团取代,而X.sub.1和X.sub.2代表氯原子或共同形成下列结构的基团:其中n为0至2,R.sub.6和R.sub.7,它们相同或不同,是氢原子或,当n=1时,可以是烷基基团,或与它们连接的碳原子一起形成环丁基基团,或下列结构的基团:其中n、R.sub.6和R.sub.7如上定义,或它们的盐(如果存在的话),以及它们的水合物,它们的制备以及含有它们的药物组合物。
