Skew-symmetric matrices of order 7 defined through the 2-fold vector cross product in C7 , and other related matrices, are presented. More concretely, matrix properties, namely invertibility, nullspace, powers and index, are studied. As a consequence, results on vector cross product equations, vector cross product differential equations and vector cross product difference equations in C7 are established.
