There are structure theorems for perfect ideals of grade 2 (Burch), grade 3 Gorenstein (Buchsbaum-Eisenbud) and some grade 4 Gorenstein (Kustin- Miller). In this article a similar structure theorem for perfect ideals of grade 3 and CM-type 2 (and with one further technical condition) is given. The structure theorem consists of a minimal free resolution of the ideal.
