The Laves graph or K 4 crystal is a theoretically predicted three-dimensional crystalline metastable carbon structure in which each carbon atom is bonded to three others, at 120° angles (like graphite), but where the bond planes of adjacent layers lie at an angle of 70.5°, rather than coinciding. [34] [35]
Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.
This image was composed by rendering the crystal structures/simulations of the allotropes using VESTAS 3.4.6 (Momma, K. and Izumi, F. 2011. VESTA 3for three-dimensional visualization of crystal, volumetric and morphology data.

Eight allotropes of carbon:a) Diamond, b) Graphite, c) Lonsdaleite, d) Buckminsterfullerene (C70), e) C540, f) Fullerene (C70), g) Amorphous carbon, h) single-walled carbon nanotube Old version. With some of the data I gathered when I made the carbon nanotube image I nominated below, I created an overview of the variety of molecular structures ...
The following allotropes belong to the second group: MP8, [8] OP8, [8] SC4, [9] BC-8 [10] and (9,0). [11] These are hypothetically quasi-stable at the high pressure. BC-8 carbon is not only a superdense allotrope but also one of the oldest hypothetical carbon structures; initially it was proposed in 1984 in the work R. Biswas et al. [10] The MP8 structure proposed in the work J. Sun et al. [8 ...
The atoms of carbon can bond together in diverse ways, resulting in various allotropes of carbon. Well-known allotropes include graphite, diamond, amorphous carbon, and fullerenes. The physical properties of carbon vary widely with the allotropic form. For example, graphite is opaque and black, while diamond is highly transparent. Graphite is ...
