Nanostructured diamonds hosting optically active paramagnetic color centers (NV, SiV, GeV, etc.) and hyperfine-coupled with them quantum memory <sup>13</sup>C nuclear spins situated in diamond lattice are currently of great interest to implement emerging quantum technologies (quantum information processing, quantum sensing and metrology). Current methods of creation such as electronic-nuclear spin systems are inherently probabilistic with respect to mutual location of color center electronic spin and <sup>13</sup>C nuclear spins. A new bottom-up approach to fabricate such systems is to synthesize first chemically appropriate diamond-like organic molecules containing desired isotopic constituents in definite positions and then use them as a seed for diamond growth to produce macroscopic diamonds, subsequently creating vacancy-related color centers in them. In particular, diamonds incorporating coupled NV-<sup>13</sup>C spin systems (quantum registers) with specific mutual arrangements of NV and <sup>13</sup>C can be obtained from anisotopic azaadamantane molecule. Here we predict the characteristics of hyperfine interactions (<i>hfi</i>) for the NV-<sup>13</sup>C systems in diamonds grown from various isotopically substituted azaadamantane molecules differing in <sup>13</sup>C position in the seed, as well as the orientation of the NV center in the post-obtained diamond. We used the spatial and <i>hfi</i> data simulated earlier for the H-terminated cluster C<sub>510</sub>[NV]<sup>-</sup>H<sub>252</sub>.
