The rare-earth pyrosilicate family of compounds (RE$_{2}$Si$_{2}$O$_{7}$)hosts a variety of polymorphs, some with honeycomb-like geometries of therare-earth sublattices, and the magnetism has yet to be deeply explored in manyof the cases. Here we report on the ground state properties ofC-Er$_{2}$Si$_{2}$O$_{7}$. C-Er$_{2}$Si$_{2}$O$_{7}$ crystallizes in the C2/mspace group and the Er$^{3+}$ atoms form a distorted honeycomb lattice in the$a$-$b$ plane. We have utilized specific heat, DC susceptibility, and neutrondiffraction measurements to characterize C-Er$_{2}$Si$_{2}$O$_{7}$. Ourspecific heat and DC susceptibility measurements show signatures ofantiferromagnetic ordering at 2.3 K. Neutron powder diffraction confirms thistransition temperature and the relative intensities of the magnetic Bragg peaksare consistent with a collinear N\'eel state in the magnetic space group C2'/m,with ordered moment of 6.61 $\mu_{B}$ canted 13$^{\circ}$ away from the$c$-axis toward the $a$-axis. These results are discussed in relation to theisostructural quantum dimer magnet compound Yb$_{2}$Si$_{2}$O$_{7}$.
