A compound of formula (I) wherein G is either (i) or (ii), where M.sup.1
or M.sup.2 is bonded to A; n is 0 or 1; when G is (i), D is S, NR.sup.7,
CR.sup.8.dbd.CR.sup.9, CR.sup.8.dbd.N, CR.sup.8.dbd.N(O), N.dbd.CR.sup.9
or N(O).dbd.CR.sup.9; when G is (ii), D is S or NR.sup.7; E is N, N-oxide
or CR.sup.10; M.sup.1 is OC(.dbd.Y), N(R.sup.11)C(.dbd.Y),
N.dbd.C(OR.sup.12), N.dbd.C(SR.sup.13) or N.dbd.C(NR.sup.14R.sup.15)
where O or N is the atom of attachment to the ring containing D and E;
M.sup.2 is N--C(.dbd.Y) where N is the atom of attachment to the ring
containing D and E; Y is O, S or NR.sup.16; J is N or CR.sup.17; and A,
