The C(6)-N(1) bond length is 1.48 Å. Both C(6)-H(9,10) bond lengths are 0.97 Å. P(1) is bonded to one C(6), one O(3), one O(4), and one O(5) atom to form PCO3 tetrahedra that share  a cornercorner with one N(1)HC3 tetrahedra. The P(1)-O(3) bond length is 1.53 Å. The P(1)-O(4) bond length is 1.52 Å. The P(1)-O(5) bond length is 1.52 Å. N(1) is bonded to one C(1), one C(4), one C(6), and one H(1) atom to form distorted NHC3 tetrahedra that share  a cornercorner with one P(1)CO3 tetrahedra. The N(1)-H(1) bond length is 0.91 Å. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(7,8) is bonded in a single-bond geometry to one C(4) atom. In the fourth H site, H(9,10) is bonded in a single-bond geometry to one C(6) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one P(1) atom. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one C(5) atom. In the third O site, O(2) is bonded in a single-bond geometry to one C(5) atom. In the fourth O site, O(3) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one P(1) atom.
