Both C(2)-C(3) bond lengths are 1.38 Å. In the third C site, C(3) is bonded in a single-bond geometry to two equivalent C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.95 Å. In the fourth C site, C(4) is bonded in a distorted single-bond geometry to one O(3) atom. The C(4)-O(3) bond length is 1.41 Å. In the fifth C site, C(7) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(8) atom. The C(7)-N(1) bond length is 1.34 Å. The C(7)-H(8) bond length is 0.95 Å. In the sixth C site, C(11) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(12) atom. The C(11)-N(1) bond length is 1.32 Å. The C(11)-H(12) bond length is 0.95 Å. N(1) is bonded in a trigonal planar geometry to one Ni(1), one C(11), and one C(7) atom. There are four inequivalent H sites. In the first H site, H(12) is bonded in a single-bond geometry to one C(11) atom. In the second H site, H(13) is bonded in a single-bond geometry to one Ni(1) and one O(3) atom. The H(13)-O(3) bond length is 0.84 Å. In the third H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(8) is bonded in a single-bond geometry to one C(7) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ni(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one Ni(1), one C(4), and one H(13) atom.
