There are complex manifolds with reduced cohomology vanishing in arbitrarily high degrees. Namely, product of two odd-dimensional spheres admits complex structure coming from representing it as a quotient of $\Bbb C^n \times \Bbb C^m$ by diagonal action of $\Bbb R$. They are known as Calabi-Eckmann manifolds.
