This paper describes an oxidative coupling catalyst composition for converting methane to a higher hydrocarbon. It comprises: a Group IIIB metal selected from the group consisting of yttrium, lanthanum and scandium; a Group IIA metal selected from the group consisting of barium, calcium, and strontium; and a Group IVA metal selected from the group consisting of tin, lead and germanium and wherein the cationic species of the Group IIIB metals, the Group IIA metals and the Group IVA metals are present in the approximate ratio of 1:0.5-3:2-4, respectively. This patent also describes a process for preparing a catalyst represented by the approximate empirical formula Y{sub 1}Ba{sub 2}Sn{sub 3}O{sub y} wherein the value of y represents the number of oxygen anions required to balance the combined charge of the cationic species Y, Ba and Sn, comprising intimately mixing an oxygen-containing compound of each of yttrium, barium and tin, and thereafter calcining the mixture at a temperature of up to about 1000{degrees}C. to produce the catalyst.
