Inclusion compounds, intercalation compounds, and solid solutions of colored organic metal compounds which contains a nickel salt or nickel complex of an azobarbituric acid or its tautomer

An inclusion compound, intercalation compound or solid solution which is a nickel salt or nickel complex, of a compound which, in one of its tauteromeric structures, corresponds to the formula ##STR19## in which the rings designated X and Y are unsubstituted or are substituted by one or two substituents from the group consisting of .dbd.O, .dbd.S, .dbd.NR.sub.7, --NR.sub.6 R.sub.7, --OR.sub.6, --SR.sub.6, --COOR.sub.6, --CN, --CONR.sub.6 R.sub.7, --SO.sub.2 R.sub.8, ##STR20## alkyl, cycloalkyl, aryl and aralkyl, the total number of the endocyclic and exocyclic double bonds for each of the rings X and Y being three,

• R.sub.6 represents hydrogen, alkyl, cycloalkyl, aryl or aralkyl and
• R.sub.7 represents hydrogen, cyano, alkyl, cycloalkyl, aryl, aralkyl, C.sub.1 -C.sub.6 -alkyl-carbonyl, phenylcarbonyl, C.sub.1 -C.sub.6 -alkylsulphonyl, phenylsulphonyl, carbamoyl, carbamoyl which is substituted by C.sub.1 -C.sub.6 -alkyl, phenyl or napthyl, sulphamoyl, sulphamoyl substituted by C.sub.1 -C.sub.6 -alkyl, phenyl or napthyl, guanyl, guanyl substituted by Chd 1-C.sub.6 -alkyl, phenyl or naphthyl,
