You wanted to know if any elements were able to match carbon's ability to form 2D sheets, nanotubes, and buckyballs.
According to https://www.azonano.com/article.aspx?ArticleID=4863 and other sources, graphene-like 2D sheet formation has (thus far) been demonstrated in the following elements:
boron, silicon, germanium, phosphorus, antimony, bismuth, arsenic, and tin
In addition, nanotube formation has (thus far) been demonstrated for all of the above except tin.
Since any element that can form a 2D sheet should be able to form a nanotube, it is expected that tin nanotubes will be developed eventually. In the meantime, computational studies have been done to predict the properties of tin nanotubes.
By contrast, the subset of the above list that has been shown to form buckyballs is, thus far, limited to boron and silicon.
The formation of buckyballs (60 atoms) involves bond length and angle constraints, which may rule out some of the elements that can form 2D sheets. Though it is possible that elements that cannot form buckyballs could form fullerenes of other sizes.
I've repeatedly added the "thus far" qualifier to indicate that these properties may eventually be demonstrated for other elements as well.
