单核金属 含有一个金属原子的有机配位化合物，是最普通的金属有机化合物。金属的配位数根据其外层空间和配位体提供的电子数而定。稀土元素的价电子少，为了满足惰性元素的电子构型,稀土元素利用其(n-1)d空轨道,甚至(n-2)f空轨道，可以与六个以上配位体相结合。过渡金属（见过渡元素）单核有机配位化合物往往遵守16或18电子构型规则，钛、锆、铪已有4个外层电子,它们与总电子数为12的配位体络合，形成 Cp2MX2式化合物(Cp为环戊二烯基，M为金属，X为卤素)；铬、钼、钨已有6个外层电子，它们与总电子数为12的配位体络合，构成18电子构型，例如Cr(CO)6；铁、钌、锇已有8个外层电子，它们与总电子数为10的配位体络合，构成稳定的18电子构型，例如Cp2Fe，或Fe(CO)5。 单核金属与有机配位体的成键方式符合配位化学规律。通常，配位体通过σ键或π键向金属输送电子，过渡金属则通过 d轨道向配位体反键轨道中反馈电子（见金属有机物的键型）。这是常见的推拉电子方式。比较特殊的成键方式是过渡金属原子与一个 sp2杂化的或sp杂化的碳原子结合，配位的碳原子，如卡宾碳处于缺电子状态，它的空p轨道可以从金属原子的d轨道获得反馈电子，即存在着 dπ-pπ键。这种类型的键存在于单核的金属卡宾中，例如：
