Abstract
This invention relates to novel platinum-diamine complexes having the formula: ##STR1## wherein R.sub.1 and R.sub.2 independently of each other may be selected from the group consisting of hydrogen, an alkyl group having 1-20 carbon atoms, a cycloalkyl group having from 3-7 carbon atoms in the ring, an aralkyl group, and an aryl group having 1-20 carbon atoms, whereas R.sub.1 and R.sub.2 together may form a cycloalkyl group having 3-7 carbon atoms in the ring and having the formula: ##STR2## wherein N is 2 to 7 and wherein R.sub.3 and R.sub.4 independently of each other are selected from the group consisting of hydrogen, an alkyl group having 1-20 carbon atoms, an aryl group or an aralkyl group having 1-20 carbon atoms in the alkyl group and X is an anionic group, providing that when X is either chlorine or malonate, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are not each H; when X is chlorine and R.sub.1 and R.sub.2 are each H, R.sub.3 and R.sub.4 are not each methyl; when X is chlorine and R.sub.1 and R.sub.2 are each methyl, R.sub.3 and R.sub.4 are not each H, and when X is chlorine R.sub.1 is hydrogen and R.sub.2 is methyl and R.sub.3 and R.sub.4 are not each hydrogen.
