$$\frac{n}{3}$$ n3 -neighbourly moment-angle complexes and their unstable splittings

Given an $$\frac{n}{3}$$ n3 -neighbourly simplicial complex Kon vertex set [n], we show that the moment-angle complex $$\mathcal Z_K$$ ZK is a co-H-space if and only if Ksatisfies a homotopy analogue of the Golod property. This gives a sufficient condition for the integral formality of $$\mathcal Z_K$$ ZK .
