The complex symplectic group Sp(2n,C)\text{Sp}(2n,\mathbb C) is the group of 2n×2n2n\times 2n complex-valued matrices that preserve the form ω\omega as in the definition of the real symplectic group.

This group is a matrix Lie group because it is a subgroup of the general linear group GL(n,C)\text{GL}(n,\mathbb C).
